Static Equilibrium lab help needed

  1. Nov 10, 2011 #1
    In a static equililibrium lab, what are some reasons why the sums of the forces and/or torques may not be equal to zero. The forces in N are very close to zero (as my professor said they should be) and the torques in N-cm are not anywhere close to zero. I know the torques are greater than their corresponding forces due to the fact they are being multiplied by a distance r as well as the sin of ∅. My professor told me that I would not get zero for either calculation, and therefore would need to tell him why the corresponding values do not sum to zero.

    Thanks
