Problem: In the frame shown,

$-$ The same cable wraps around the pulleys at C$,$ D$,$ and G$.$

$-$ The pulley at $\backslash ($ D $\backslash )$ is kept in balance thanks to the action of pin $\backslash ($ P $\backslash ).$

$-$ Member EF is a hydraulic cylinder, which acts as a two$-$force member.

$-$ The pulleys at $\backslash ($ C $\backslash )$ and $\backslash ($ D $\backslash )$ have a weight of $0\mathrm{.}5$ kN each.

$-$ Members $\backslash ($ A B C $\backslash )$ and $\backslash ($ A E $\backslash )$ weigh $3$ kN and $2$ kN $,$ respectively.

Find the forces acting on:

a$)$ members $\backslash (\backslash$mathrm$\{$ABC$\},\backslash$mathrm$\{$AE$\}\backslash )$ and BDE

b$)$ pins $\backslash (\backslash$mathrm$\{$A$\},\backslash$mathrm$\{$C$\}\backslash )$ and E $,$

c$)$ pulleys C$,$ D$,$ and G;

At the end, the FBD of each of the above elements must be presented neatly, indicating the forces with their correct magnitudes and directions.
