>>12280875Depending on your track within mechanical/civil/aero, you might have to go back to statics and mechanics of materials again and again. You can't do structural analysis of frames and trusses, finite element analysis, or elasticity without knowing how to draw a free body diagram or solving for reaction forces at supports.
But you might be thinking of something like RF, controls, software, or w/e so that's where my knowledge stops.
