Задача 10845.

Located horizontally homogeneous cylinder of radius R can rotate around an axis which coincides with its geometrical axis. Friction axis creates not dependent on the speed of rotation moment. To the cylinder at the level of the axis of a point mass m is attached and released without shock. Define: at what minimum value of m will rotate the cylinder; m at what he do? turn, stop.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
