A bicycle wheel can be thought of a uniform hoop with a radius of 48 cm and mass 1.6 kg. Consider the case where the wheel start from rest and accelerates uniformly under the action of a constantly applied torque of 0.5 N-m exerted by a force at the edge of the wheel. The torque is caused by the bicycle chain acting at a radius of 11.5 cm from the center of the wheel. (a) How long does the wheel take to reach a speed of 10 rev/min? (b) Through how many revolutions does it turn while accelerating? Your Answer: Answer
One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts at a 36.1o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.
When you hold an ball by only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.80 kg. The biceps is connected to the forearm a distance of 2.50 cm from the elbow, and it holds a 44.5 N (about 10 lbs) ball at the end of the forearm at distance of 35.0 cm from the elbow. What is the magnitude of the torque about the elbow by the ball, in N·m? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A 2.0 m long, 200 N uniform ladder, rests with one end against a smooth wall making an angle of 30° with the wall. The coefficient of static friction between the ground and the lower end of the ladder is 0.5.
