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, (a) What torque are you exerting? (b) If 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, (c) Do your answers depend on the direction of your push relative to the direction of the wrench handle?
