The bone breaks if stress greater than 1.50 x 10⁸ N/m2 is imposed on it. (a) What is the maximum force that can be exerted on the male humerus in the upper arms if it has a minimum effective diameter of 5.87 cm? (b) If this much force is applied, by how much does the 27.0-cm-long humerus stretched? Assume Young’s modulus for bone is 1.50 x 10¹⁰ Pa.
