How much force must be produced by the biceps brachii, attached at 90 degrees to the radius at 4.0 centimeters from the centre of rotation of the elbow joint, to support a weight of 95 newtons held in the hand at a distance of 32 cm from the elbow joint? Assume that the forearm and hand have a combined weight of 35 newtons and that their center of gravity is located 17 cm from the elbow joint.
