2. A human biceps(upper arm muscle) may exert a force of the order of 600N (about 135 Ib) on the bones to which it is attached. If the muscle has a cross- sectional area at its center of 50 cm^2=0.0050 m^2, and the tendon attaching its lower end to the bones below the elbow joint has a cross section of 0.50 cm^2=5.0x10^-5 m^2, find the tensile stress in each of these cross sections.

When a tension of 70 N is applied to a piano wire of length 1.8 m, it stretches by 2.0 mm. If the same tension is applied to a similar piano wire of length 3.6 m, by how much will it stretch?
A person places his hand palm downward on a scale and pushes down on the scale until it reads (8.31x10^1) N. The triceps muscle is responsible for this arm extension force. Find the force (in N) exerted by the triceps muscle. The bottom of the triceps muscle is 2.50 cm to the left of the elbow joint, and the palm is pushing at approximately 35.0 cm to the right of the elbow joint. (please ignore the number 96 shown in the scale). Give your answer with three significant figures.
80. Between each pair of vertebrae in the spinal column is a cylindrical disc of cartilage. Typically, this disc has a radius of about 3.0 X 10-² m and a thickness of about 7.0 x 10-3 m.
