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?

Possible Answers:

Correct answer:

Explanation:

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:
