Homework Help: Simple quesiton involving Tension of a cable supporting a beam

  1. Oct 3, 2009 #1
    1. The problem statement, all variables and given/known data

    Determine the tension in the cord if the weight is 90kg

    3. The attempt at a solution

    The tension is the same throughout the rope apparently so;

    = T(2) - (4/5)T(4) - 882.9N(5.5)
    T= 933.383N...

    would that be the force in the cable then? i don't have to worry about Ay or Ax because that is my pivot point then right?

    Hi mike41! :wink:
    Yes, you choose A as the point to take moments about precisely because you don't want to be bothered with the reaction forces at A. :smile:
    erm … why is one T minus? :redface:
