1. The problem statement, all variables and given/known data http://uploader.ws/upload/201009/problem.jpg 2. Relevant equations Sum Fx=0 Sum Fy=0 displacement=alpha*(DeltaT)*L displacement=sum of (P*L)/(A*E) 3. The attempt at a solution I'm really not even sure where to start. I have a FBD drawn with Fb, Fc, and Fd and these equations written down, but not really sure where to go from there.
