## Please help me with this fundamental Mechanics of Materials problem.

1. The problem statement, all variables and given/known data

(please see the attachment)

2. Relevant equations

σ=F/A

3. The attempt at a solution
I just can't figure out how to find the forces in the two members.
Actually I thought the force in both members will be the same, but according to the problem statement it clearly isn't that way.
Kindly help me with this.

 Recognitions: Gold Member Homework Help Science Advisor You should determine the end reaction at C first, using the equilibrium equation in the x direction. C will be a function of the unknown force P. Then a FBD of each part will give the force in that part, then set the stresses in each part equal to solve for P. Please show your workings.
 Yeah, I got it. Thanks :)
