Question

The maximum internal compressive stress that the bone can withstand is 1.6 × 10⁸ N/m². The femur is the largest and longest bone in the human body. The cross-sectional area of ​​the femur is 7.7 × 10^-4 m². Find the maximum intensity of the compressive force that can be applied without breaking the femur. (Answer: F = 123.2 kN)

Answer 1

$\sigma=F/A\to F=\sigma\cdot A=1.6\cdot10^8\cdot7.7\cdot 10^{-4}=$

$=123200\ (N)=123.2\ (kN)$ . Answer
