Consider the frame below. The cable is attached at the end of the beam at $F,$ passes over a frictionless pin at $C,$ and is attached to the fixed support at $B.$ A uniform loading is applied to the bottom member and a constant tension runs in the entire cable. The frame is pin$-$connected to the wall at A$.q,$

Answer the following questions:

$($a$)$ Calculate the tension in the cable and the reaction forces at A$.$ Include a free$-$body diagram. $(7$ marks$)$

$($b$)$ Section the frame vertically at $D$ and calculate the internal loads, i$.$e$.$ the normal force, shear $(8$ marks$)$ force, and bending moments there.
