Determine the local x displacements at each end of the bars

Question

For the bar elements shown in Figure, the global displacements have been determined to be u₁ = 0:5 in., v₁ = 0:0, u₂ = 0:25 in., and v₂ = 0:75 in.

Determine the local x displacements at each end of the bars. Let E = 12 106 psi, A = 0:5 in², and L = 60 in. for each element.
