Example Question #1 : Other Mechanical Forces
A wrench is being used to tighten a bolt. The center of the bolt is the pivot point, and the wrench is long. If a force of is applied at the midpoint of the wrench and that force is parallel to the wrench, what is the torque?
The equation for torque is
The force is applied meters from the pivot. and in this case because the force is parallel, the perpendicular component of force is zero, so:
