Homework Help: Which of these is false about torque

  1. Jul 6, 2008 #1
    Which of these is false about torque:
    1) torque is 0 unless the force is pointed perpendicular to the moment arm
    2) it can only be prodcued by a force
    3) torque may pt cw or ccw, depending on direction the force points

    I don't know which one of these is false. They all seem pretty true to be, although I suspect #2.

    think about it, what if the force is at a 45 degree angle to the moment arm? Would the torque be 0 in that case?
