Repeat Prob. 3–134 but determine the maximum shear stress and depth for the steel ball.
Repeat Prob. 3–134, A carbon steel ball with 25-mm diameter is pressed together with an aluminum ball with a 40-mm diameter by a force of 10 N. Determine the maximum shear stress, and the depth at which it will occur for the aluminum ball. Assume Fig. 3–37, which is based on a typical Poisson’s ratio of 0.3, is applicable to estimate the depth at which the maximum shear stress occurs for these materials.
