With reference to $2-$D rigid$-$body equilibrium system shown in Figure $6,$ what is the moment of the tension in cable CD about A$?$ In keeping with convention,

take the positive direction of rotation to be counter$-$clockwise.

A$.T_{CD}[cos()q+sin()(r+s)]$

B$.T_{CD}[sin()q+cos()(r+s)]$

C$.T_{CD}\sqrt[\phantom{2}]{(r+s{)}^2+q^2}$

D$.T_{CD}[sin()q-cos()(r+s)]$

E$.W_r$
