Solve Problem 7.3 using Castigliano’s theorem.

Problem 7.3

If the flexural rigidity EI of each of the propped cantilevers shown is constant, determine the expression for the deflection at the mid-span of each beam in terms of the load, the span L and flexural rigidity using the principle of virtual work.
