Two cylinders are to be press-fitted together so that the principal stress with the greatest absolute value is not to exceed 60 percent of the yield strength of the material. Both members are made of a steel with a yield strength of 80 ksi, E = 30 Mpsi, and v = 0.29. The nominal diameters of the cylinders are 1.0, 1.5, and 2.0 in. (a) Determine the maximum acceptable radial interference and the corresponding interface pressure. (b) Under the conditions of part (a) plot the stress distributions for each member.
