HI, Thanks for the reply. Here is where i am stuck At A-B There is No load so dM/dP= 0 and dU/dP= 0 At B-C M = -px - wx.x/2 dM/dP= -x dU/dP = Wx^4/8EI At C-D M = -Wb + Px dM/dP = x dM/dP = -Wbx^2/ 2EI When i include all vaues to compute total starin energy, (AB+BC+CD)...

Pls help me to solve this..
