The piston of an automobile engine is held to the connecting rod by a wrist pin having an external diameter of 20 mm and internal diameter of 11 mm. The length of the bearing in the rod end is 25 mm and the bearing in each boss of the piston is 15 mm. The maximum load transmitted is 14.50 kN. (a) Determine the bearing pressure between the rod end and the wrist pin. (b) Compare the maximum bending stress in the pin, assuming that it is a simple beam with a uniform load. Please solve completely ?
