Directions: Solve the following probiems and show your solution. 1. The length of a bicycle pedal arm is 0.152 m, and a downward force of 111 N is applied to the pedal by the rider's foot. What is the magnitude of the torque about the pedal arm pivot point when the arm makes an angle of (a) 30°, (b) 90°, and (c) 180° with the vertical?
