The minimum cross-sectional area of a human Femur bone is 4.5 x10-4 m². The maximum compresional load at which fracture occurs is Hint: Ultimate compresion strength for bones o = 17 x 107 N/m². Ultimate tension strength for bones of = 12 x 107 N/m2. a) 59500 N b) 76500 N c) 60000 N d) 66000 N e) 54000 N

Answer :

Final answer:

The maximum compressional load at which fracture occurs is 76500 N.

Explanation:

The maximum compressional load at which fracture occurs can be calculated using the formula:

Maximum Compressional Load = Ultimate Compression Strength * Minimum Cross-sectional Area

Plugging in the given values, we have:

Maximum Compressional Load = (17 x 107 N/m²) * (4.5 x 10-4 m²)

Simplifying the expression, we get:

Maximum Compressional Load = 76500 N

Therefore, the correct answer is b) 76500 N.
