a. A rotary lever with a length of 0.43 m rotates 12radians when a force of 239 N is applied to it. What is the maximum possible work this lever can do in newton-meters?

b. Pushing down on a bicycle pedal with 959 N of force, the pedal fixed at 0.20 m from the center of the gear moves through 30 of angle. What is the work innewton-meters thatyou do to effect this motion?
