Homework Help: Torque and Equilibrium

  1. Nov 14, 2007 #1
    1. The problem statement, all variables and given/known data

    A meter stick with a mass of 235 g is supported horizontally by two vertical strings, one at the 0 cm mark and the other at the 90 cm mark

    2. Relevant equations

    t=r F sin θ

    3. The attempt at a solution

    F1=the first string at zero
    F2=the second string

    F1+F2-235=0

    (F1x0)+(F2x90)-(235)=0

    Careful: 235 is the mass (in grams), not the weight.

    Same problem as above plus one more: Where does the weight of the stick act?
