The pipe has an outer diameter of 80 mm and an inner diameter of 70 mm. Determine the average normal stress in the aluminum core and steel pipe, if a tensile force of 200 kN is applied to the rigid ends. SOLUTION: Force equilibrium requires that the tensile force in the steel pipe and the aluminum core adds up to the total tensile force, expressed as follows: 200 kN st al FF  Furthermore, elongation due to tensile force in the pipe and the core should be the same. st al    22 2
