Torque of suspended meter stick

  1. Nov 8, 2009 #1
    1. The problem statement, all variables and given/known data
    A uniform 1.0-N meter stick is suspended horizontally by vertical strings attached at each end. A2.0-N weight is suspended from the 10-cm position on the stick, another 2.0-N weight is suspendedfrom the 50 cm position, and a 3.0-N weight is suspended from the 60 cm position. What is the tension in the string attached at the 100-cm end of the stick?
    a. 1.9 N
    b. 3.0 N
    c. 3.5 N
    d. 4.0 N
    e. 4.4 N

    2. Relevant equations

    sum of torques and sum of forces

    3. The attempt at a solution


    i get the tension to be 3 but the correct one should be 3.5, i dont see where i lose the .5 newtons

    Re: Torque

    Does the meter stick have mass? Where does the torque for the stick's mass act?
