A patient's leg was put into traction, stretching the femur from a length of 0.46 m to 0.461m. The femur has a diameter of 3.05 cm. With the knowledge that bone has a Young's modulus of 1.6 100 in tension, what force was used to stretch the femur? 9. A force of 40 N applied at the end of a wire of length 4 m and diameter 2.00 mm produces an extension of 0.24 mm. Calculate the (a) stress on the wire; (b) strain on the wire; (c) Young's modulus of the material, (d) Identify the material.
