Q4. Figure Q4 shows a steel column that pinned on top and fixed at the base. The column is restrained by steel beams about its x-axis and y-axis on the top of the column. The radius of gyrations of the column about x-axis is 137 mm and y-axis is 77.8 mm. The Modulus Elasticity of the column is 200 x10 kPa. (i) Calculate the moment of inertia of the column on x axis and y axis. (17 marks) (ii) Find...
