How much does the femur shorten when a 70-kg person stands on one foot? Assume that in the absence of stress, the femur has a length of 0.5 m. The femur’s cross-sectional area can be modeled as a hollow circular tube with internal diameter d1 = 2.5 cm and external diameter d2 = 3.3 cm. Young’s modulus for bone compression is 9 × 109 N/m2.

During a wrestling match, a 140 kg wrestler briefly stands on one hand during a maneuver designed to perplex his adversary. By how much (in m) does the upper arm bone shorten in length? The bone can be represented by a uniform rod 38.0 cm in length and 2.10 cm in radius. Assume Young's modulus for bone under compression is 9 ✕ 109 N/m2. m
