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. [/PLAIN] [Broken] 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.
