Two structural links are connected at the origin O$.$ One has a $1$ kN applied force and the

other an unknown compressive force F$2.$ The origin O is also supported by the $2$ kN

tension in a cable and the unknown force in another rope OA$.$

Find:

a$)$ The compressive force F$2$ and the force on the rope OA given that the system is in

static equilibrium.

$($When youre finding F$2$ and the unknown force in rope OA can you show step$-$by$-$step the algebraic process when solving for the unknown variables.$)$
