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.

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 :)
