The studying continues, as does my amazement that I actually have a degree in this subject. Two degrees, even! I am supposed to be an "expert" and yet I forgot half these things existed, and forgot how to deal with the other parts.

As a freshman engineer, you take two courses in chemistry, two courses in physics, and two in math. That leaves room for exactly one actual engineering course: STATICS. Statics is the litmus test by which you determine if you actually want to be an engineer or not. Most did not.  In order to make it through statics you need to be (a) good at it, or (b) lazy enough that you can't be bothered to change majors. I was (b). Yay? Anyway, onto the learning!

Free body diagrams. Last seen in Dynamics, junior year. Oh, how I hate you free body diagrams. The only thing I hate more than drawing you is admitting how utterly important you are to correctly solving a complicated Statics problem.

Friction over a pulley. Last seen... actually, I'm not entirely convinced I've ever done this kind of problem before. Probably last seen in Statics, freshman year. That whole year is kind of a haze, honestly.

Centroids. Last seen in Dynamics, junior year. Dynamics was pretty much the last gasp for alot of this bullshit, before I left mechanics behind for good to study heat and mass transfer. Oh, yeah, that's right: heat AND mass transfer, baby. I'm sure there's a terrible nerd pickup line in their somewhere, but I'm too tired to tease it out.

Moments of inertia. Last seen in Dynamics, junior year. I sucked at calculating them then, and I suck now. I mean, length to the fourth power? What the hell does that even mean outside of hypercubes? And God help you if you are ever trapped in a hypercube. Speaking of which...
