Question about axis of rotation for torque! (would really appreciate some help!)

  1. Oct 6, 2011 #1
    Hi Guys so I would really appreciate if I could get some help with this question I have, I have a test in a couple days!

    So we are learning about torque and there are a couple components of torque that I'm a bit confused about.

    1. Is the axis of rotation a line or just a point?

    2. Is the lever arm the shortest length b/t the "line of action" and the axis?

    Thank you very much!
