Solved: An AISI 1018 steel ball with 1-in diameter is used
Chapter 3, Problem 3-137(choose chapter or problem)
An AISI 1018 steel ball with 1-in diameter is used as a roller between a flat plate made from 2024 T3 aluminum and a flat table surface made from ASTM No. 30 gray cast iron. Determine the maximum amount of weight that can be stacked on the aluminum plate without exceeding a maximum shear stress of 20 kpsi in any of the three pieces. 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.
