Solve Example $4-4$ below using element connectivity order as shown in Table $1,2$ AND $3.$ Show in detail the steps and proof that using the element connectivity order as suggested has something to do with angle or orientation of the truss element but does not affect the final answer.Example $4-4$For a plane truss shown, determine: a$)$ displacements at nodes $2$ and $3$; b$)$ stresses in each element; c$)$ reaction forces at the supports.Use: E$,=29\mathrm{.}5$ x $106$ psi and A $=1$ in$?$ for all elements.
