Question $1(50$ points$)$ The frame shown is made of a horizontal handle and a vertical rod AB$.$ The horizontal handle is pin connected at its one end and a force of $P=1$ kip is applied to its other end. The vertical rodAB is pin connected at its ends A and $B.$ The vertical rod $AB$ is made of $A-36$ steel with Modulus of Elasticity of $E=29000$ksi and has a circular cross$-$sectional area with diameter of $1\mathrm{.}25in.$ Determine the displacement of end A with respect to end B$.$
