Torque: Equilibrium of a Rigid Object Experiment 11
... When several forces act on an object, there are generally two effects: the object’s center of mass translates and the object rotates about some axis. Under certain conditions, the object can be in translational and rotational equilibrium at the same time. The purpose of this experiment is to study t ...
