1. The problem statement, all variables and given/known data

2. Relevant equations
Fr (resultante force) = 0
Sum of all forces aplied at the strut = 0
Sum of the torque of all forces = 0

3. The attempt at a solution
I started by analysing the torque, since the strut is on static equilibrium and I ended up having C (tension on the cable) = W. However, when I applied that relation to the system of equations that studies the sum of all forces applied at the strut, I ended up having no conclusion.

Hi RodiRego,

Can you show your work ? C = W says little about the strut staying in place !

A good start. Because the angles are equal the $\Sigma \tau$ with the foot of the strut as axis of rotation didn't bring you any further.
But you can do a lot with the force balance at the foot ! Make sure you don't forget any force contributions.
