Mechanical Engineering Major
Mechanical Engineering is the design and analysis of machines, engines, and mechanical systems. It is a major within Engineering & Technology.
Mechanical Engineering is the study of how machines and mechanical systems work, from engines and turbines to robots and HVAC systems. Students learn to design, build, and improve devices that move, rotate, or transfer energy. The discipline asks questions like: How should a part be shaped to handle stress? What materials will work best? How can a system be made more efficient or reliable? To answer these, mechanical engineers combine knowledge of physics, materials science, and mathematics with hands-on problem-solving skills.
The major typically begins with foundational coursework in physics, mathematics, and basic engineering principles that apply across all machines. As students progress, they take more specialized classes in areas such as thermodynamics, mechanics of materials, fluid dynamics, and control systems. Throughout the curriculum, students apply these concepts to real-world design challenges, often working in teams on projects that require them to think critically about tradeoffs between cost, performance, safety, and practicality. The field attracts people who are curious about how things work and enjoy combining analytical thinking with creative design.
Typical coursework
Course requirements vary by school, but a Mechanical Engineering program commonly includes topics such as:
- Statics and dynamics
- Thermodynamics
- Fluid mechanics
- Materials science
- Machine design
- Heat transfer
Most programs also include general-education requirements and, in many fields, a capstone project, internship, or research experience.
Degree levels
Mechanical Engineering is commonly offered at these levels:
- Bachelor's
- Master's
- Doctoral
Availability differs by institution, and program names can vary (for example, a Bachelor of Arts versus a Bachelor of Science track).
Common career directions
Graduates with a Mechanical Engineering background pursue a range of paths. Some roles related to this field of study include:
- Mechanical engineer
- Design engineer
- Manufacturing engineer
- HVAC engineer
Many careers require additional steps beyond the major — such as a graduate degree, a license, or a certification — and many graduates work in fields unrelated to their major. What you study is one factor among many in where your career goes.
