Resultant force on a pulley system

  1. Jan 30, 2013 #1
    1. The problem statement, all variables and given/known data

    Could anyone give me an idea of how to start this problem to work out the resultant force's magnitude, direction and couple in the top (alternator) pulley?

    Does the 30° angle affect the equations? As all the notes I have seem to only have pulleys with the force at each side in parallel to one another other. Also the system is running at a constant speed.


    2. Relevant equations

    I believe the equation needed is radius times force but again I can't seem to find any notes on how to answer this question.

    3. The attempt at a solution

    How to start the question is what I'm asking help with

    Thanks for any help!

    Yes, the angle affects the resultant.
