The maximum compressional stress that a bone can withstand is 1.6 × 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 × 10−4 m2. What is the maximum compressional force that can be applied to the thighbone? (a) 2.1 × 1011 N, (b) 1.2 × 105 N, (c) 4.8 × 1012 N, (d) 3.0 × 103 N, (e) This cannot be determined since Young’s modulus is not given.

Question
The maximum compressional stress that a bone can withstand is 1.6 × 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 × 10−4 m2. What is the maximum compressional force that can be applied to the thighbone?
(a) 2.1 × 1011 N, (b) 1.2 × 105 N, (c) 4.8 × 1012 N, (d) 3.0 × 103 N, (e) This cannot be determined
since Young’s modulus is not given.
