Torque

In this interactive activity adapted from Wake Forest University, learn about torque. Observe the rotational motion of a beam pivoting about a central axis and see how a mass's horizontal distance from the pivot point determines the rotational force it exerts. Watch as masses are added to either side of the beam at various distances to create different amounts of torque, and see how a variety of combinations can be used to reach equilibrium. In addition, see how it becomes easier to loosen a bolt when a wrench handle is extended to increase torque.

This media asset was adapted from Wake Forest University: Physics Demo Videos.
