Question $20$: The beam in the figure is pinned on the left$-$hand side $($Point A$)$ and supported by a vertical roller at the right$-$hand side $($Point D$).$ A moment load of $800N*m$ is acting at point B while a rope is attached to the beam at point $C$ and directed over a frictionless pully as shown. Determine the tensile force $T$ in the rope such that the internal shear in the entire segment CD of the beam becomes zero.

$F_x$:$A_x+T=C$

$Ax$:$-T$

a$)T=533kN$

b$)T=200kN$

c$)T=100kN$

d$)T=250kN$
