Static Equilibrium - Tension, Torque, Lever, Beam, & Ladder Problem - Physics

This physics video tutorial explains the concept of static equilibrium - translational & rotational equilibrium where everything is at rest and there's no motion. This video contains plenty of examples and practice problems.
