Quick Q: Static Equilibrium

  1. Jul 23, 2015 #1
    1. The problem statement, all variables and given/known data
    screenshot_8.png

    2. Relevant equations
    Net Force = 0
    Net Torque = 0

    3. The attempt at a solution

    At the support point
    , is there a horizontal force component?​

    This is irrelevant to the solution of the problem, why do you think it is an issue?

    You can do that if you want, but the question you should ask yourself once you have done that is: can I compute the result without knowing the answer to the question you just asked?

    I know the message you want to give me .. I would take net torque around the support point so all forces from it will have 0 torque.
    But i asked the question because there must be horizontal force produced from there. because there is only single horizontal force genrated from rope. so there must be a balancing force

    Yes, you can assume there is sufficient friction at the support to prevent it slipping.

    Just to add: Otherwise it will slip and not be in equilibrium.
