Problem $5$

In the structure shown in the figure, the horizontal rod was made $\backslash (\backslash$delta $\backslash )$ too short. The structure was then assembled. Calculate the internal forces and stresses in the rods if all the rods are made of the same ma with Young's modulus E$.$ Cross$-$sectional area A$,$ angle $\backslash (\backslash$alpha $\backslash ),$ and distance $1$ are known as well. $\backslash (\backslash$delta $\backslash$ll $1\backslash )$ A drawing with displacement analysis is required. Moreover, proper equations etc.
