Mechanical engineers design, analyze, build, and fix anything that moves, heats, cools, or carries load: engines, machines, HVAC systems, medical devices, and factory equipment. The job comes down to one loop: understand a requirement, turn it into a design, prove with math and testing that it works, then fix what fails. Most US employers want an ABET-accredited bachelor's degree (52% of workers hold one), though about 29% enter through an associate's degree and grow from there.

Stage 1 of 4 · about 16 weeks
Learn statics, dynamics, and basic strength of materials. Do calculus and physics problems daily. Draw simple parts by hand and in free CAD. Learn to read engineering drawings and basic GD&T symbols. Finish with one small part modeled and dimensioned.
Calculus and physics problem fluency
Every mechanical formula you will use is calculus and physics in disguise. If you can set up a problem, the rest of engineering is mostly applying patterns. Daily short practice beats weekend cramming.
Statics
Statics is the base of all structural and machine design. Before you can say whether a bracket, shaft, or frame will hold, you must know what forces act on it. It is also the most common first exam in engineering interviews and coursework.
Dynamics
Machines move. Engines, linkages, conveyors, and vehicles all depend on how forces create motion. Dynamics lets you predict speeds, accelerations, and energy so you can size motors, springs, and brakes.
Basic strength of materials
Knowing a force is not enough; you must know if the part survives it. Strength of materials connects loads to stress and deformation, and is how you decide a dimension or choose a material.
Engineering drawings, basic CAD, and GD&T
Drawings are how engineers hand designs to machinists and suppliers. Reading them is a core task of the job, and a part modeled cleanly in CAD is the first thing a hiring manager wants to see.
