Another torque question (no math)

  1. Nov 16, 2008 #1
    1. The problem statement, all variables and given/known data
    What is the relationship between the counter clock wise torque and the clock wise torque when the system is in equilibrium?



    2. Relevant equations



    3. The attempt at a solution
    The counter clock wise has a positive value and clock wise has a negative value. The negative and positive values don't matter because the sum of all forces is zero anyways?

    Key work here is "equilibrium" which means the torque is not causing rotational acceleration.

    Your statement, "The negative and positive values don't matter because the sum of all forces is zero anyways?" is a bit off, but I know what you mean and it's basically correct. But it's not the values don't matter, it's that they are equal. Also, it's the sum of the moments that is equal to zero for rotational systems in equilibrium, not forces.
