Given That A Grip Force Of 2 Lb Is Applied To The Right Brake Lever The Brake Pad And Rim Have A Coefficient Of Fricti 1 (69.76 KiB) Viewed 26 times

Given that a grip force of 2 lb. is applied to the right brake lever, the brake pad and rim have a coefficient of friction of 0.35, the tire and the road have a coefficient of friction of 0.7, (just for simplicity, use these values for both kinetic and static friction) and assuming perfect efficiency of all components in the mechanism, A. Find the pinching force of the brake pads on the rear wheel's rim. B. Find the frictional braking force applied to the rear wheel by the brake pads when the pinching force from Part A is applied. (In normal situations, the frictional force from the brake pads on the rim creates a roughly equal braking force between the tire and the ground.) C. Consider using the rear brake to either (1) lock the rear wheel and skid/slide the tire against the road, or (2) keep the wheel rolling without slipping on the road. Now answer the questions below: • Where does most of the kinetic energy go if the braking rear wheel is skidding? • Where does most of the kinetic energy go if the braking rear wheel is rolling?
