The solution is done using Castigliano's theorem. We shall place an imaginary load p where we want to find the deflection.
Potential Energy U =
After integration of the potential energy deflection, (delta) =
After differentiating with imaginary load p. substitute p =0 in it.
There is a little bit of integration we need to do (cumber some)
Kindly go through every step for better understanding.
All the best.!
I hope you shall understand.
