Homework Help: Pivoting Cylinder

  1. Oct 5, 2008 #1
    1. The problem statement, all variables and given/known data

    M, a solid cylinder (M=1.63 kg, R=0.119 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder with a mass m = 0.830 kg is hung from the string, find the angular acceleration of the cylinder.


    2. Relevant equations

    torque = I(alpaha)

    3. The attempt at a solution

    I tried to solve the problem algebraically, and got (2mR)/(MR^2 - 2mR^2) but I keep getting it wrong.
