A 13-kN hydraulic press for removing and reinstalling bearings in small-to medium-sized electric motors is to consist of a commercially available cylinder mounted vertically in a C- frame, with dimensions as sketched in the Figure shown below. It is being proposed to use ASTM A-48 (Class 50) gray cast iron (brittle material with ultimate strength, Su= 345 M P a) for the C-frame material. Calculate the maximum bending tensile stress in M P a?
