Frames: Consider the pulley and frame system below. The radius of each pulley is $250mm$ and the weight of each component can be neglected. Determine:

$($A$)$ the reaction force at $E,$vec$(R{)}_E,$

$($B$)$ the reaction force at $E,$vec$(R{)}_D,$ and,

$($C$)$ the internal components of shear, $V,$ bending moment, $M,$ and normal force, $N,$ at point $F.$ Point $F$ is halfway between A and $C.$ Be sure to include the appropriate sign on the internal forces according to the customary sign convention.
