Homework Help: Conceptual question on transitional and rotational equilibrium

  1. Nov 8, 2008 #1
    3 forces act on an object. If the object is in translational equilibrium, which of the following must be true?
    1. the vector sum of the forces =0
    2. the magnitude of the 3 forces must be equal
    3. the 3 forces must be parallel

    would the answer be just 1? I don't think 2 is true because the forces can be unequal but the net force needs to be = 0. And I don't know how what's stated in choice 3 must necessarily contribute to translational equilibirum. Thanks for any imput.
