Question

A man with a mass of 67.8 kg stands on one foot. His femur has a cross-sectional area of 8.00 cm^2 and an uncompressed length of 51.3 cm. Young's modulus for compression of the human femur is 9.40 × 10^9 N/m^2. How much shorter is the femur when the man stands on one foot? What is the fractional length change of the femur when the person moves from standing on two feet to standing on one foot?

Step 1

Given: - Mass (m) = 67.8 kg - Cross-sectional area (A) = 8.00 cm^2 = 8.00 x 10^-4 m^2 - Uncompressed length (L) = 51.3 cm = 0.513 m - Young's modulus (Y) = 9.40 x 10^9 N/m^2 Using the formula for deformation (delta): \[ \delta = \frac{m \cdot g \cdot L}{A \cdot Show more…
