1. The problem statement, all variables and given/known data M, a solid cylinder (M=1.67 kg, R=0.137 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder pulls downward with a force F which equals the weight of a 0.670 kg mass, i.e., F = 6.573 N. Calculate the angular acceleration of the cylinder. 2. Relevant equations F*R ? ang accel. = alpha*R 3. The attempt at a solution I multiplied Force*Radius, cause someone told me to start with that, but I'm not sure what to do next? Do I have to use a=9.81 m/s^2? I'm not really good at this stuff so if someone could help me that would be great!! thanks!
