solid mechanics.ENERGY METHOD (Castigliano's) theorem.dont copy paste other tutor, pls do your own

5. A structure ABC is loaded as shown in Figure Q5. The whole ABC has a diameter of 50mm. Taking E=80GPa, determine a) the Castigliano's equations for vertical deflection at B and slope at C b) the total strain energy stored in the structure c) the horizontal deflection of the structure at C. (Ans: a)xB,v=PdU,C=MdUb)U=[(EI1P2+EA1P2)AB+(6EI1P2)BC] c) xC,h=(EI2P+EA2P)AB+(6EIP)BC
