Engineering Mechanics
from first principles

The two courses every engineering student takes together, regardless of which faction they end up in. Statics first — learning why things stay still — then Dynamics, adding time and asking why they move. The same free body diagram vocabulary runs through both; the only thing that changes is whether ΣF equals zero or ma.
