Static Equilibrium

A self-checking practice quiz on static equilibrium for a calculus-based physics course: the two conditions for equilibrium, the net force and net torque conditions, torque and the lever arm, balancing torques, solving for unknown forces on beams, ladders and supports, choosing a pivot, the center of gravity, and the types of equilibrium. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
