Answer to Question #50401 in Mechanics | Relativity for Ali

Question

A hollow right-circular cylinder is made of cast iron and has an outside diameter of 75 mm and an inside diameter of 60 mm. If the cylinder is loaded by an axial compressive force of 50 kN, determine the total shortening (in mm) in a 600 mm length. Also, determine the normal stress (in MPa) under this load. The modulus of elasticity of cast iron is E = 100 GPa.
