Equation for torque of a cylinder, a hollow cylinder, and a sphere.

  1. Mar 1, 2010 #1
    1. The problem statement, all variables and given/known data

    What is the equation for the torque of a cylinder, a hollow cylinder, and a sphere rolling down an incline?

    2. Relevant equations

    This is what I don't know

    3. The attempt at a solution

    I have no idea where to start.

    Torque is the rate of change of angular momentum

    if angular momentum = Iω, that is torque then?

    What is the equation for torque? Similarly to F = ma, the equation for torque is
    [tex]T[/tex] [tex]=[/tex] [tex]I[/tex][tex]\alpha[/tex]
