In this part . . .
This part is all about equilibrium, the state of balance between opposing forces. Here, I discuss Newton's basic laws of motion and their applications in statics. I provide the basic equilibrium formulas and show you how to compute unknown support reactions from free-body diagrams. Plus, I also explain the differences between two- and three-dimensional techniques for evaluating equilibrium conditions.
