Consider the frame shown in Figure $2,$ with a constant modulis of elasticity, E$,$ and a varying moment of inertia, $\backslash ($ I $\backslash )($refer to the values provided in Figure $2).$ Using the Force Method of analysis, compute ail the reaction forces at A and D $.$ Take $\backslash ($ D$\_\{$x$\}\backslash )$ as the redundant $($i$.$c$.,$ horizontal resction at D$).$ Use units of kips for forces and foot for length throughout the problem.

Hint: Use the $\backslash ($ x $\backslash )-$coordinates shown in the figure to formulate your moment equations, Do not forget to transfer the forces from the vertical members to the horizontal one!
