A 92-kg man's thighbone has a relaxed length of 0.51 m, a cross-sectional area of 6.3 10-4 m2, and a Young's modulus of 1.2 1010 N/m2. By how much does the thighbone compress when the man is standing on both feet? In um?
The upper surface of a cube of gelatin, 7.0 cm on a side, is displaced 0.78 cm by a tangential force. If the shear modulus of the gelatin is 950 Pa, what is the magnitude of the tangential force? In N?
