FBD with Applied Torques in Angled Member

  1. Oct 5, 2010 #1
    1. The problem statement, all variables and given/known data

    I have a member that is at a 15 degree angle from the horizontal. I have a purely vertical load acting halfway along it, and an applied torque at one end. I am solving for the torque at the other end.

    2. Relevant equations

    Equilibrium equations.

    3. The attempt at a solution

    My question is this: Because I am working in a non-angled reference frame, I have naturally used Lcos(15)*vertical load in my moment equilibrium equation. But how do I account for the applied torque? I don't think it needs to be multiplied by cos(15) as torques in an equilibrium equation are independent of their distance from the equilibrium point, but I would like to verify this. Thanks!
