5 (a) State and prove the Castigliano's theorem. (10 mars) (b) A steel strut is of square section 100mm X 100mm over the middle portion, which is 150mm long and 70mm X 70mm over the remainder length. If the total length is 250mm and the lond 800KN, calculate the total strain energy in the bar. E = 200GN/m'. (10 marks)
