Problem: In the frame shown,

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

$-$ 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 ABC and AE weigh $3$ kN and $2$ kN $,$ respectively.

Find the forces acting on:

a$)$ members $\backslash ($ A B C$,$ A E $\backslash )$ and $\backslash ($ B D E $\backslash )$

b$)$ pins A$,$ C 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.
