A basketball hits the hoop with a force of 2.5 lb at an angle of 75 degrees from the horizontal. The distance between the outer rim of the hoop and the backboard (point A) is 18 in. What is the moment/Torque created at the backboard (moment/Torque about A due to force of basketball) in units of in lb?
The forearm-hand complex weights 51N, and the center of mass is 0.17 m from the elbow joint. The person is holding a large wheel of cheese that weighs 98N. The center of mass of the cheese is 0.34 m from the elbow joint. The moment arm of the elbow flexors is estimated to be 0.03m from the elbow. The relative elbow angle is (angle between the humerus and the forearm) is 60°. What force must be exerted by the elbow flexors to keep the forearm in this static position (in N)?
