What is Mechanical Engineering?
Mechanical engineers play an important role in many industries, from automotive and aerospace to biotech and and computer electronics. A mechanical engineering job typically involves:
- Multidisciplinary teamwork
- Data interpretation
- Customer service
Mechanical engineers design and manufacture everything from small parts like bearings to conveyor systems and other large equipment. Examples of products that mechanical engineers can design and develop are:
- Internal combustion engines
- mechanical components
- aircraft engines
- control systems
- medical devices
- disk drives
- gas turbines
- wind turbines
- fuel cells
- thermal devices
- machine tools
They also read and interpret blueprints, technical drawings, schematics and computer-generated reports. Other mechanical engineering skills include problem-solving, testing, operations, technical communication, sales and administration.
What is mechanical engineering?
Virtually any machine or process you can think of has benefited from the cultivation of the mechanical engineering degree and profession. Your day-to-day activities are influenced by the work of mechanical engineers: driving an automobile; riding in an elevator; buying packaged foods; and turning on your air conditioning mechanical system. We have access to affordable and convenient technologies such as refrigeration, microwave cooking, transportation, communication, and copying because mechanical and other engineers worked together to make it happen.
Mechanical engineers influence how new technologies are created and applied, whether in sustainability, materials, robotics, and fields as diverse as aerospace engineering to biomedical engineering.
Is mechanical engineering the right career field for you? Are you curious, methodical, rational, analytical, and logical? Mechanical engineers have distinct personality traits. To be a successful professional engineer, you must like to investigate how things work and how to make them better.
What doES A mechanical engineer do?
If you're interested in the mechanical engineering field, we've outlined several of the most important mechanical engineering skills. A successful mechanical engineer will:
- Analyze a problem to figure out how a mechanical device might solve the problem, applying physics, engineering, mathematics and material science principles
- Design the device and create blueprints so the device can be built
- Develop and test a prototype
- Analyze the test results and change the mechanical design as needed
- Oversee the manufacturing process, traveling to various sites to make sure the specifications are followed
To design and manufacture mechanical systems, mechanical engineers need to have a deep understanding of mechanical processes, electronic product manufacturing, mechanics, dynamics, thermodynamics, electricity, and structural analysis.
They need to be good at computer-aided engineerings, such as CAD (computer-aided design); and CAM (computer-aided manufacturing), to produce and analyze their designs, as well as to monitor the quality of products. If computer-aided engineering catches your eye, take a look at our article detailing what computer engineering is.
In addition to computer expertise, mechanical engineers should have these skills:
- Ability to solve problems; analytical thinking
- Teamwork, communication and leadership
- Excellent math skills
- Sound knowledge of engineering principles
- Ability to prepare designs and cost estimates
- Ability to read and interpret drawings and specifications
- Understanding of machining and fabrication processes
- Able to write technical reports
- Ability to present to coworkers and customers
Mechanical engineers should have excellent oral and written communication skills and enjoy working with others as team players. Often, mechanical engineers develop products for clients who do not understand mechanical engineering terminology.
When you are considering which mechanical engineering program you want to pursue, make sure that your education prepares you for both the engineering technology and mechanical design aspects of mechanical engineering, but also the soft skills like being able to effectively communicate your ideas to a room of non-engineers.
What fields are in mechanical engineering?
According to the Bureau of Labor Statistics, U.S. Department of Labor, the largest employers of mechanical engineers are:
- Architectural, engineering and related engineering services: 22 percent
- Machinery manufacturing: 13 percent
- Transportation equipment manufacturing: 12 percent
- Scientific research and development services: 7 percent
- Computer and electronic product manufacturing: 7 percent
Your career might focus on heat exchangers, refrigerators, ventilation systems, technologies that include use of lasers, precision machinery, and nanotechnology; biomedical devices; and modeling of machinery and systems using virtual reality.
Is mechanical engineering a good career?
For job prospects and opportunities, mechanical engineering careers offer good potential among occupations that involve science and math. The average annual salary is above $87,000 and the Bureau of Labor Statistics projects that the field of mechanical engineering will grow by 9 percent between 2016 and 2026.
Higher rates of growth will occur in fields like automotive design for hybrid cars, electric cars and driverless cars. Or you might consider becoming a robotics engineer or explore mechanical engineering jobs in fields like alternative fuels, sustainability and nanotechnology.
Here are a few specific mechanical engineering careers:
They are responsible for creating robots and robotic systems that are able to perform duties that make human jobs safer, easier and more efficient. The technical focus of the mechanical engineering program at North Central College is on automation and robotics.
Automotive research engineer
They work to improve the performance of automobiles, trucks, tractors and other vehicles by improving traditional suspensions, aerodynamics and alternative fuels. They design new products, modify existing ones, troubleshoot and solve problems.
Heating and cooling systems engineer
They work in a specialized field called heat engineering, also known as heat transfer or thermal sciences. Heating and cooling systems engineers develop systems that maintain temperatures and humidity for airplanes, trains, cars, computer rooms, hotels and schools.
They develop, process and test materials to address problems in other engineering fields.
They apply biology and biochemistry to engineering to address evolving technologies like surgical robots and advanced prosthetics.
If you find yourself curious about other engineering disciplines such as a degree in computer engineering or wondering, "What do electrical engineers do?", North Central College is excited to discuss these career paths with you so you can make the best decision that aligns with your passions.
Do mechanical engineers need a master’s degree? Bachelor’s degrees or dual-degree in engineering qualify mechanical engineers for entry-level positions. A master’s degree in mechanical engineering prepares you for promotions to roles like team leader and project manager. You might consider a master’s degree program that focuses on more advanced engineering principles or an interdisciplinary program that combines other sciences and/or business courses.
TAKE YOUR FIRST STEPS TOWARDS A MECHANICAL ENGINEERING DEGREE
At a college like North Central College, your engineering education will train you in the necessary mechanical skills and prepare you to explain complex machines, devices, and ideas to people; strong communication skills are necessary to express your ideas clearly and effectively.
Engineering majors at North Central College enroll in a broad general education curriculum designed to help them become interdisciplinary thinkers and communicators. Future professional engineers can also prepare for their careers by conducting research with their professors and participating in co-curricular activities to round out their undergraduate engineering education.
