Mechanical Engineering

Designing machines and physical systems, from engines to robots.

Content last reviewed: August 2026

Mechanical engineering is one of the broadest engineering disciplines, covering how things move, how forces act on structures, and how energy is converted and used. Core coursework builds a physics-and-math foundation (statics, dynamics, thermodynamics, fluid mechanics) before applying it to design.

Most programs are lab- and project-heavy, with hands-on work in machining, CAD modeling, and increasingly robotics, since mechanical engineers are expected to move between designing on a computer and building physical prototypes.

Typical courses you might take

✓Statics & Dynamics
✓Thermodynamics
✓Fluid Mechanics
✓Mechanics of Materials
✓Machine Design
✓Heat Transfer
✓Computer-Aided Design (CAD)
✓Senior Design Project
