SUMMARY
The discussion centers on calculating the angular acceleration of a solid cylinder with a mass of 1.63 kg and a radius of 0.119 m, which pivots on a frictionless bearing. A mass of 0.830 kg is suspended from a string wrapped around the cylinder. The user attempted to derive the angular acceleration using the formula torque = I(alpha) and arrived at the expression (2mR)/(MR^2 - 2mR^2), but reported repeated errors in their calculations. Clarification and assistance from other forum members are sought to identify the mistakes in the algebraic solution.
