Question

The table below provides data concerning the shrink fit of two cylinders of differing materials and dimensional specifications in inches. The Young's Moduli of the steel, aluminum and the cast iron are 190GPa,71.7GPa and 100GPa respectively. Poisson's ratio is 0.305 for steel, 0.333 for aluminum, and 0.211 for cast iron. Identify the radial interference , the interference pressure p, and the tangential normal stress on both sides of the fit surface. If dimensional tolerances are given at fit surface, repeat the problem for the highest and lowest stress level. (Due to the tedious calculations, the last two cases with * are considered additional points) 6.
