For the bar elements shown in Figure P$3-16,$ the global displacement have been deter$-$

mined to be $u_1=0\mathrm{.}5in.,v_1=0\mathrm{.}0,u_2=0\mathrm{.}25in.,$ and $v_2=0\mathrm{.}75in.$ Determine the

local $x^{\text{'}}$ displacements at each end of the bars. Let $E=12{10}^6,A=0\mathrm{.}5i{n}^2,$

and $L=60$ in$.$ for each element.
