- The d = 12-mm-diameter solid rod passes through a D = 20-mm-diameter hole in the support plate. When a load Pis applied to the rod, the rod head rests on the support plate. The support plate has a thickness of b = 13 mm. The rod head has a diameter of a = 29 mm, and the head has a thickness of t = 8 mm. If the normal stress produced in the rod by load Pis 225 MPa, determine (a) the bearing stress acting between the support plate and the rod head. (b) the average shear stress produced in the rod head. (c) the punching shear stress produced in the support plate by the rod head.
