Q1. A 750-pound boat sits on a ramp inclined at 60 degree, what force is required to keep the boat from rolling down the ramp? Q2. A child applies the brakes on a bicycle by applying a downward force of 20 pounds on the pedal when the crank makes a 40 degree angle with the horizontal as shown. The crank is 6 inches in length. Find the torque at P. 6 in. 40° F = 20 lb
