$($a$)$ Calculate the reaction forces at the support A and G$.$

$($b$)$ Use the Method of Joints to find the load on

members CD$,$ DE$,$ CE$,$ EF$,$ BE and BC$,$ respectively.

Please assume that the weight of each member is very

small in comparison with the loads.

In your answers, indicate the nature of the load $$

use $($ C $)$ for compression and $($T$)$ for tension.

$($Hint: Note that Ay $=0$ due to the rollers$).$

Please show all steps, thank you.
