Asked by Bret
A 89.0 kg person stands on one leg and 90% of the weight is supported by the upper leg connecting the knee and hip joint-the femur. Assuming the femur is 0.640 m long and has a radius of 1.90 cm, by how much is the bone compressed?

You will need to look up Young's modulus (Y) for femur bone material.
Then use
deltaL = L*(stress)/Y
Stress = M g/area
Then use
deltaL = L*(stress)/Y
Stress = M g/area
