Static Equilibrium problem

  1. Apr 11, 2016 #1
    1. The problem statement, all variables and given/known data
    problem.png

    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, :welcome:

    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.

    A Free-Body-Diagram for the rod should let you finish the solutionm.
