The maximum compressional stress that a bone can withstand is 1.6 ã 108 n/m2 before it breaks. a thighbone (femur), which is the largest and longest bone in the human body, has a cross sectional area of 7.7 ã 10â4 m2. what is the maximum compressional force that can be applied to the thighbone?

The maximum compressional force that can be applied to the thigh bone is 123.2kN  Ans.
