Q$1.[1\%]$

$($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$)$
