Case Studies That Define Mechanical Engineering Challenges

Mechanical Engineering

Mechanical engineering is key in creating and perfecting the machines and systems we rely on every day. To truly grasp its complex challenges, it’s useful to look at detailed case studies.

These studies not only show how engineering works but also highlight why keeping people safe, coming up with new ideas, and making ethical choices matter so much.

Let’s explore some major events that tested mechanical engineering. We’ll look at the fix of the Hubble Space Telescope, how Mars Rovers were made to move on another planet, why the Tacoma Narrows Bridge fell apart, the nuclear crisis at Fukushima Daiichi, and the massive oil spill from Deepwater Horizon.

Each story breaks down how mechanical engineering played a role and what we can take away from these incidents to prevent future mistakes and guide new breakthroughs in the field.

The Hubble Space Telescope Repair

Mechanical engineers faced tough problems when fixing the Hubble Space Telescope. To tackle these, they combined deep knowledge with creative thinking. They carefully checked the telescope’s parts to find what was broken.

Then, they came up with special tools and steps for the astronauts to fix the telescope in space, where conditions are very difficult. They used a method called finite element analysis to make sure the telescope would be strong enough after the repairs, and they made sure that new parts could be swapped in easily.

Their detailed planning and work didn’t just get Hubble working again; it also made sure the telescope could keep working for a longer time. This shows how important mechanical engineering is in solving tough problems with machinery in space.

Mars Rover Mobility Dilemmas

Building Mars rovers is a tough job for mechanical engineers. They have to make sure these rovers can move smoothly over Mars, which has a very rough surface with lots of rocks, sand, and big hills. Engineers work with advanced robot technology, new types of materials, and knowledge about other planets to solve these problems.

They test their designs over and over to see how the rover parts will handle the ground on Mars. The parts have to be really strong and not wear out quickly, even when they hit unexpected bumps.

Also, the rovers need smart computer systems that can figure out the lay of the land by themselves and change their path to avoid getting stuck or broken. This is super important because if something goes wrong with the rover, it could mess up the whole mission to Mars.

Tacoma Narrows Bridge Collapse

The Tacoma Narrows Bridge collapse is a key example for mechanical engineers of why it’s essential to consider how wind affects bridges. When the bridge fell apart in 1940, it showed that suspension bridges can swing and twist dangerously in the wind.

The bridge’s narrow shape, the solid pieces it was made of, and not enough side support were big reasons why it moved so much and then broke. This disaster made it clear that testing bridges in wind tunnels was necessary.

As a result, bridge design changed a lot. Engineers started using special devices to stop bridges from swinging too much and created stronger design rules. These changes help make sure that big bridges can stand up to wind without getting damaged.

Fukushima Daiichi Nuclear Disaster

The Fukushima Daiichi nuclear disaster is a crucial lesson in the need for strong and reliable engineering. On March 11, 2011, a huge earthquake, with a strength of 9.0, shook Japan and caused a major failure at the Fukushima Daiichi Nuclear Power Plant. This event showed how important it is for machines and structures to be able to survive natural disasters like earthquakes and tsunamis.

After the earthquake, a tsunami followed, which made things even worse. The power plant lost power, which meant the cooling systems for three of its reactors stopped working. Without cooling, these reactors overheated and their cores melted down. This was a tragic example of what can go wrong when we don’t carefully think about the risks of building in areas where natural disasters can happen.

Later on, experts looked at what went wrong and found that the power plant wasn’t built to handle a tsunami of that size, and the emergency plans weren’t good enough for such a disaster. Now, the Fukushima disaster is a key example that engineers study. It shows the link between planning ahead, considering the environment, and the serious problems that can happen if we don’t.

Deepwater Horizon Oil Spill Engineering

In April 2010, the Deepwater Horizon oil rig failed disastrously, causing a huge oil spill in the ocean. This event was significant because it showed how much we needed to improve our deep-sea drilling technology and how we respond to such disasters. Engineers had to look closely at how they build and check the safety of underwater equipment, such as blowout preventers, which are supposed to stop leaks. They also needed to make sure oil wells were designed to be very strong and could handle emergencies.

The spill made it clear that we must do better at predicting risks, watching over drilling as it happens, and creating tools that can handle the tough conditions at the bottom of the sea. After the spill, experts worked on making better plans for how to deal with such problems, which included using more advanced robots that can work underwater and creating better ways to quickly block leaking oil wells.

Engineers learned a lot from what happened with the Deepwater Horizon. They are using those lessons to try to make drilling in deep water safer, to reduce the chance of another big oil spill. This means continuing to develop new technology and safety measures that can prevent or quickly stop leaks if they do happen.

In summary, every case study shows different problems that mechanical engineers have to deal with.

For example, fixing the Hubble Space Telescope needed very accurate work, and getting the Mars Rover to move on Mars took a lot of creativity.

The fall of the Tacoma Narrows Bridge and the nuclear accident at Fukushima Daiichi teach us that strong design and having a backup plan are very important.

The oil spill at Deepwater Horizon reminds us that safety features and thinking about the environment are essential.

These examples show that mechanical engineering involves many different areas and that it’s important to keep coming up with new ideas and to watch out for possible risks.

Welcome to the Mechanical Engineering Case Studies website. Select your course from the list at the Left to begin.

This web site is being developed to give undergraduate Mechanical Engineering students real engineering examples and experimental data in their lecture courses. This is done by using design calculations or experimental data completed by ME seniors in their design courses, lab courses, honors thesis, and Co-op (with permission from the company). Results from graduate student research or published experimental data are also used. This allows students to become familiar with data analysis and the inherent uncertainties in experimental measurements before entering the laboratory courses.

The case studies are formatted as a homework assignment. In some cases, the entire case study would be assigned for homework. In other cases, there are several similar sets of data and only one set of data would be assigned for homework. Each case study includes a description of the objectives, the experimental facility, and the experimental procedure used to obtain the data. When possible, photos and video clips are used to show the facility and experimental procedure. From the web site, students can download engineering drawings of the models used in the experiment and spreadsheets containing the experimental data. The web site describes the data analysis required in the assignment. Included in the data analysis may be nondimensionalization, statistical analysis, plotting the experimental data, and comparison of the experimental results with correlations found in the text.

In this case study web site you will also find several ethics case studies and several links that have been found for particular classes. A statistics tutorial gives a review of the statistical analysis that is used in several case studies.

If you are interested in contributing additional case studies, or have any comments or suggestions regarding this site, please contact Professor Laura Pauley ( [email protected] ).

Case Study use in Mechanical Engineering Design Workshop - ME 380

Case implementation storyboard in me 380, case background.

The Dalsa Harmony Camera Body Part Design case study was developed in 2013 and intended for use in Mechanical Engineering and System Design courses covering topics such as design, manufacturing and heat transfer. The scope and specific topics covered by the case study are broader than the base material taught in the targeted courses. The case documents the design of a camera cover, the parts fabrication process, and a heat sink thermal analysis by Teledyne Dalsa Engineers and University of Waterloo coop student.

The Harmony camera body part design is based on Dalsa’s existing camera and specifically targets reduced production costs with comparable performance, scalable component architecture and lower bill of materials (BOM) costs. The project design focuses on the camera assembly, specifically reducing fabrication costs of the Harmony camera body components (H-Section, a 3D printed model of which is shown in Figure 1) while maintaining adequate heat transfer performance. The H-section is the structural housing to which key electronic components are attached, and it transfers heat away from these components via an internal heat sink bridge. In the existing camera, the H-section is manufactured from billet aluminum. A more cost-effective solution was desired for the Harmony camera.

In ME 380, the student used Design for Manufacture and Assembly (DFMA) methodology to simplify Harmony camera mechanical parts in terms of minimizing the number of parts, and minimizing the time and therefore costs of the assembly process. The case solution modules also cover topics in material selection and cost estimation, presenting trade-off decisions for alternate designs. Case materials include the case study itself, solution modules, teaching note and presentations.

Course Description

The case was used in the mechanical engineering design course (ME 380 - Engineering Design Workshop) in fall 2013 to instruct 87 students. The course consisted of both lectures and other case study analyses. During the lectures, the topics in the competency material were discussed. That formed the basis for the discussion of the case studies by student teams during case delivery.

The course (ME 380) is a third year design project core course. The Dalsa case was used to emphasize design for manufacturing concepts and provide a real-world application of manufacturing process analysis and cost estimation during product design. Students were provided with a sample 3D printed version of the mechanical part, Figure 2. The Dalsa Harmony Camera Design case study was assigned during the last week of the term after covering the needed theoretical concepts in the course.

Preparation

The case and individual assignments were provided to the students one week in advance of the implementation date, after an introductory lecture on DFMA. During the individual assignment phase, questions were designed mainly to demonstrate students’ ability to use appropriate knowledge and skills to: identify, formulate, analyze and develop substantiated solutions to a real-world problem. The students worked individually and in teams to analyze the problem and come up with their own recommendations about the manufacturing process and estimated cost. Often, individual study and preparation are followed by small group discussions, either in or outside of class. In this implementation, the class instructor (Nespoli) presented the case.

The class presentation focused on addressing most of the questions given to the students as part of their individual preparation assignments. Students were assigned to a team of 4 people and asked to discuss their individual answers in these teams in class, spending roughly 10 minutes on each question. The small group discussions facilitated the development of the students’ ability to verbally communicate complex engineering concepts to group members. As part of the small group discussions, a number of different manufacturing methods for the H-section were suggested and discussed in class.

Student Reaction

At the end of the case study in ME 380, students were asked to complete a feedback survey; 81 of 87 students responded. They were asked to respond to 5 questions on a Likert scale, from 1 (strongly disagree) to 5 (strongly agree). Figure 3 shows the student response to question 1: This case study was an engaging application of these specific course topics . The majority of students either agreed or strongly agreed with this statement. Engagement is a strong prerequisite for learning, and case studies provide a real-world application of course topics which students respond to. When asked to expand on their responses, students most often cited the strong fit between the case study and the course material. The numerical average of the student responses for this question was 4.3.

Question 2 further explored the connection between the case and the course material: This case study improved my appreciation for the relevance of these specific course topics . Similar results were obtained, with a numerical average of 4.2. Students highlighted the strong connection between the theoretical concepts discussed in class and the real-world practical example in the case.

Question 3 addressed student perception of their understanding of the material: This case study helped me understand these specific course topics . The numerical average of these responses was a little lower, 3.7. While students appreciated the application of course material, and one student commented on the increased perspective the case provided, a closer connection was desired. Two interesting responses were that a “high level [treatment] does not help understand low level concepts” and that while this was related to course content, “it feels unrelated since we don’t have design questions outside of this.” This hints that more time spent on the case and/or a design approach may help.

Question 4 addressed the perceived value of small group discussions: Small group discussions of the case helped me understand the specific course topics . Figure 4 shows the distribution of responses for this question. The numerical average of these responses was 3.6. Positive responses included the fact that the discussions “created an interactive environment with classmates” and “helped to clear the doubt and solved problems that couldn’t be solved sitting alone.” The primary reason for neutral or negative responses was the lack of time for these discussions.

This is an important point. To get the most out of this learning approach, more time is required for discussion. In business school applications, students are more familiar with the case approach and are trained to have these small group discussions before class, so that class time can be devoted to full class discussions. This is not feasible for the present situation, where only one or two cases are used in a class. This means that more class time should be set aside for small group discussions, which would require removal of some course content. A trade-off is necessary between content and case learning objectives.

Figure 3: Student response to question 4: Small group discussions of the case helped me understand the specific course topics.

Students were also asked to provide general feedback for improvement of the case study and case activities. About half of the respondents suggested different time allocations. The amount of time available to present the case and the logistics should be cut back, including the presentation of background material, and the case should be introduced earlier in the term to allow for more guidance on what was expected. This would make the discussions more efficient. Some requested a more challenging problem, while others suggested a more open-ended topic, with less detail provided, might provide more scope for discussion.

Key Takeaways

The results of the first implementation of this case study are encouraging. The students appreciated the added learning provided by this approximation to practice to lectures and examples provided by the instructor. The 3D printed artifact was an important focus of the group discussions as confirmed by observations by the instructor. One of the 13 groups working on the case study arrived at the design solution adopted by Dalsa. A possible extension of the case study would be to have groups estimate the manufacturing cost of the new process.

Emerging Trends in Mechanical Engineering

group around table looking at prototype of wind energy

From tiny, tooth-scrubbing robots 1 to rockets capable of deep space exploration, 2 the field of mechanical engineering is on the cutting edge of new technologies. These exciting advancements are both powered by and driving mechanical engineering. If you want to stay relevant in this fast-paced industry, you need to stay up to date on the latest trends. 3

Read on to explore several of the most recent mechanical engineering trends and ways in which they’re likely to be implemented in the near future.

Sustainable Engineering and Renewable Energy

Sustainable engineering is the integration of sustainability principles into the design, operation and disposal of mechanical systems and products. Sustainability involves focus on reducing environmental impact, enhancing efficiency and promoting the use of renewable resources. Increasing awareness of climate change and environmental degradation is driving the demand for sustainable engineering solutions. 4

Governments, industries and consumers are seeking more eco-friendly products and energy sources. 5 As a mechanical engineer, you may be involved in designing and refining energy-efficient technologies such as more effective wind turbines and improved solar panels and geothermal energy systems. 6

Digitalization and Industry 4.0

Digitalization and Industry 4.0—the process of integrating digital technology into industrial and manufacturing processes—are transforming mechanical engineering , leading to what many call the Fourth Industrial Revolution. This revolution is characterized by the smart factory, where machines and products are connected to devices that allow for real-time tracking to optimize production efficiency and performance. Digital technologies are being incorporated into all aspects of engineering, from design and prototyping to the manufacturing process and maintenance. By combining robotics, real-time data and artificial intelligence, smart factories can make adjustments as soon as they’re needed, often without the need for human intervention. 7

The Internet of Things (IoT)

The Internet of Things involves embedding sensors, software and other technologies into physical mechanical systems, allowing them, through wireless connectivity, to exchange data with other devices and systems over the internet. For example, by equipping inventory with sensors, organizations can track it from the time it’s produced until it’s delivered to the buyer. Engineers can also use IoT technology on factory machines to monitor performance and receive alerts regarding maintenance issues before an outage or failure. 8 This integration results in smarter, more responsive systems that can adapt to changing conditions and user needs, such as statistical usage data on a product that engineers can use to improve subsequent designs. 9

Automation and Robotics

Automation employs control systems, such as computers or robots , and information technologies to handle different processes and machinery in an industry to replace human intervention. In mechanical engineering, this translates to increased efficiency, higher production rates and improved safety in manufacturing processes.

Robots are used to perform complex tasks and those that are dangerous, tedious or in need of precision beyond human capability—assembling small, intricate components, for example, or drilling in dangerous areas. They protect humans and increase productivity and consistency in assembly operations.

Additive Manufacturing Through 3D Printing

Additive manufacturing—specifically, 3D printing—may not seem trendy or revolutionary. The first 3D printer was invented in 1981, but they weren’t commercially available until 2006. 10 Though the technology has been around for years, we're seeing increasingly sophisticated new advancements in uses, techniques and materials. Niche companies, such as Relatively Space, are using 3D tech to custom-print parts on a low-volume basis. The Terran R rocket, for example, is the world’s first 3D-printed, reusable rocket. 11

One of the earliest and still primary uses of 3D printing is rapid prototyping. It allows designers and engineers to create, test, and modify prototypes quickly, dramatically reducing the development time and cost. Additionally, just-in-time production eliminates the need for expensive volume requirements and inventory storage. 12

Advanced Materials and Nanotechnology

Nanotechnology is revolutionizing mechanical engineering by enabling the development of advanced materials with unprecedented properties. Lightweight and high-strength new materials, such as carbon fiber composites and advanced alloys, are being designed for enhanced durability and performance, significantly benefiting the aerospace and automotive sectors, among others. 13

Nanotechnology allows mechanical engineers to manipulate materials at the molecular level to achieve desired performance characteristics, leading to innovative solutions in product design and manufacturing. Nanomaterials, with their exceptional strength, conductivity and thermal properties, are finding applications in many industries, including electronics, energy storage and biomaterials. 14

Artificial Intelligence (AI) and Machine Learning (ML)

Applications in optimization and decision-making.

AI and ML algorithms can be used to optimize design processes and create more efficient and effective mechanical systems. These algorithms can analyze vast datasets to identify the best design parameters, considering factors like material properties, environmental impacts and manufacturing constraints. In the manufacturing industry, AI and ML help to optimize production processes, increase production efficiency, reduce waste and improve quality. They can predict the outcomes of process changes, guide decision-making and automate routine tasks. 15

Intelligent Control Systems and Autonomous Machinery

AI allows for intelligent control systems that can autonomously adjust operating parameters in real-time for optimal performance. These systems are used in various applications, from climate control in buildings to adaptive control in manufacturing processes.

AI and ML power autonomous machinery, such as self-driving vehicles, drones and robotic systems. In mechanical engineering, benefits of these technologies include automating jobs that require high precision, improving safety by reducing human errors and advancing human knowledge through applications such as deep space exploration. 16

Predictive Maintenance and Condition Monitoring in Mechanical Systems

AI and ML are advancing maintenance strategies in mechanical engineering through predictive maintenance and condition monitoring. These technologies use data from sensors and historical records to accurately predict machine failures, allowing for proactive maintenance to prevent breakdowns.

Continuous monitoring of equipment conditions with AI algorithms—analyzing factors such as vibration, temperature and sound—facilitates early issue detection, reducing downtime and maintenance costs. Implementing AI in these areas improves the reliability of mechanical systems and their safety by averting potential hazardous failures. 17

Democratizing design through AI

Lyle Regenwetter Hometown: Champaign, Illinois Advisor: Assistant Professor Faez Ahmed Interests: Food, climbing, skiing, soccer, tennis, cooking

Lyle Regenwetter finds excitement in the prospect of generative AI to "democratize" design and enable inexperienced designers to tackle complex design problems. His research explores new training methods through which generative AI models can be taught to implicitly obey design constraints and synthesize higher-performing designs. Knowing that prospective designers often have an intimate knowledge of the needs of users, but may otherwise lack the technical training to create solutions, Regenwetter also develops human-AI collaborative tools that allow AI models to interact and support designers in popular CAD software and real design problems.

Carlos Díaz-Marín designs and synthesizes inexpensive salt-polymer materials that can capture large amounts of humidity from the air. He aims to change the way we generate potable water from the air, even in arid conditions. In addition to water generation, these salt-polymer materials can also be used as thermal batteries, capable of storing and reusing heat. Beyond the scientific applications, Díaz-Marín is excited to continue doing research that can have big social impacts, and that finds and explains new physical phenomena. As a LatinX person, Díaz-Marín is also driven to help increase diversity in STEM.

Jimmy McRae aims to drastically improve diagnostic and therapeutic capabilities through noninvasive health-care technologies. His research focuses on leveraging materials, mechanics, embedded systems, and microfabrication to develop novel ingestible electronic and mechatronic devices. This ranges from ingestible electroceutical capsules that modulate hunger-regulating hormones to devices capable of continuous ultralong monitoring and remotely triggerable actuations from within the stomach. The principles that guide McRae’s work to develop devices that function in extreme environments can be applied far beyond the gastrointestinal tract, with applications for outer space, the ocean, and more.

Freestyle BMX meets machine learning

Eva Nates Hometown: Narberth, Pennsylvania Advisor: Professor Peko Hosoi Interests: Rowing, running, biking, hiking, baking

Eva Nates is working with the Australian Cycling Team to create a tool to classify Bicycle Motocross Freestyle (BMX FS) tricks. She uses a singular value decomposition method to conduct a principal component analysis of the time-dependent point-tracking data of an athlete and their bike during a run to classify each trick. The 2024 Olympic team hopes to incorporate this tool in their training workflow, and Nates worked alongside the team at their facilities on the Gold Coast of Australia during MIT’s Independent Activities Period in January.

Augmenting Astronauts with Wearable Limbs

Erik Ballesteros Hometown: Spring, Texas Advisor: Professor Harry Asada Interests: Cosplay, Star Wars, Lego bricks

Erik Ballesteros’s research seeks to support astronauts who are conducting planetary extravehicular activities through the use of supernumerary robotic limbs (SuperLimbs). His work is tailored toward design and control manifestation to assist astronauts with post-fall recovery, human-leader/robot-follower quadruped locomotion, and coordinated manipulation between the SuperLimbs and the astronaut to perform tasks like excavation and sample handling.
