Homework Help: Calculate the pull on the high bar of a gymnast

  1. Oct 4, 2011 #1
    Calculate the pull on the high bar of a gymnast performing a giant swing. His angular velocity is 2 rads, his mass 80 kg and effector radius of rotation (distance from bar to CofG) is 1 meter

    Hi... im a bit confused... "pull on the bar" would this be the work done on the bar to the person?

    Any idead where I should be heading? Torrque or work done = fd ?

    Re: Torque?

    What happens when you swing a mass about a point?
