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)...
Any one can help me solving this pleasezzzz
