Q8. A short vertical column consists of a hollow steel tube of 48 mm outside diameter and 40 mm inside diameter with a solid brass rod of 34 mm diameter within it. The steel tube is 380 mm long and the brass rod is 1 mm shorter. The brass rod is supported on a raised boss so that the top of the tube and the top of the rod are level.

Calculate the maximum load that can be applied to the column so that the compressive stress in the brass rod does not exceed 50 MN/m².

Note: For steel, Modulus of Elasticity = 210 GN/m²

For brass, Modulus of Elasticity = 80 GN/m²
