1) As structural steel rod has a radius R = 9.5 mm and a length L = 81 cm. A force F = 6.2 × 104 N (about 7 tons) stretches it along its length.

(a) What is the tensile stress in the rod?

Note: Tensile stress is the Force of the load per unit area of the rod's surface.

(b) What is the elongation (d) of the rod under this load? What is the strain?

Note: Strain is the ratio between the elongation of the rod, and the rod's original length without the load.

2) The femur, which is the principal bone of the thigh, has a minimum diameter in an adult male of about 2.8cm, corresponding to a cross sectional area A = 6 × 10-4 m2. At what compressive load would it break? Ultimate strength for bone in compression is 170 × 106 N/m2
