A cast iron pipe of external diameter 300 mm and internal diameter 250 mm is flled with concrete and the composite is subject to an axial load of 900 kN. What will be the stresses in the cast iron and concrete? The cast iron has a modulus of elasticity of 140 GPa and the concrete a modulus of elasticity of 14 GPa.
