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 × 10³N E)This cannot be determined since Young's modulus is not given.

The maximum compressional force can be calculated using the formula: Force = Stress × Area. Substituting the given values, Force = (1.6 × 10^8 N/m^2) × (7.7 × 10^-4 m^2) = 1.232 × 10^5 N, which is approximately 1.2 × 10^5 N.
