Acarbon 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 a typical poisson's ratio of 0.3, is applicable to estimate the depth at which the maximum shear stress occurs for these materials.
