Can you answer a$,$ b$,$ c$,$ and d please?:

a$)$ Calculate tension $BC$ in the cable.

b$)$ Determine the length of the cable.

c$)$ Determine how many $[$the minimum number of$]25lb$ weights are required at $F$ to maintain a static system.

d$)$ Considering the answers from above, determine the reaction forces at $E$ and $G.$

$[$Hint: begin with the cable, then analyze the beam.$]$

$[$Hint: assume that the roller connection at Point $G$ can only resist gravity loads, and cannot resist uplift.$]$
