Textbook Question

Chapter 8, Problem 45RCQ

To tighten a bolt, you push with a force of 80 N at the end of a wrench handle that is 0.25 m from the axis of the bolt.

What torque are you exerting?
You move your hand inward to be only 0.10 m from the bolt. To achieve the same torque, show that you should exert 200 N of force.
Do your answers depend on the direction of your push relative to the direction of the wrench handle?
