young's modulus?

0 ⤊

bone has a young's modulus of about 18E9 Pa. Under compression, it can withstand a stress of about 160E6 Pa before breaking. assume that a femur is .50 m long, and calculate the amount of compression this bone can withstand before breaking

Young's modulus YM = stress/(dL/L)
The maximum compression strain
dL/L = breaking stress/YM = 0.008889
dL = 0.5 m * 0.008889 = 0.004444 m.
