Homework Statement



I need to find the Exact Solution for this problem(Displacements)
I already did it using MATLAB but I need to compare it to the exact solution
I am not sure what equations to use for this problem and where to start?

Homework Equations



-Plane strain
-E and v are given
-no thickness
-length of members are in ( )

The Attempt at a Solution



Break it into four elements and find the force on each side
i.e E2, E3 and E4 have forces pulling but I am not sure what to do about the sharing force for (2) inbetween E3 and E4 and E2 and E4

If anyone can help it would be greatly appreciative
