Question

The length of a bicycle pedal arm is 0.152 m. If a downward force of 85 is applied to the pedal by the rider at an angle of rotation of the pedals 30 degrees from the vertical determine the torque exerted on the bicycle. Hint: Draw a sketch to make sure you have the angles right. The correct units for torque are Nm.

The free body diagram below represents a 1 500 kg car sitting on a 3 000 kg bridge supported at its far ends. The car's position is three quarters of the length L from the left end of the bridge. Identify the one error in the torque equation below: a. never produces a torque on the bridge no matter where the axis of rotation is placed. b. never produces a torque on the bridge no matter where the axis of rotation is placed. c. cannot produce a torque on the bridge no matter where the axis of rotation is taken since it is at the center of the bridge. d. Because the perpendicular distance to from the left end of the bridge is 0, F1L should be 0. e. Because the perpendicular distance to from the right end of the bridge is 0, F2L should be 0.
