The flywheel having a moment of inertia J = 245 kg * m ^ 2 is rotated, making n = 20ob / s. After the wheel torque has ceased to operate, it is stopped by making N = 1000 rpm. Find: 1) the friction torque M; 2) the time r, elapsed from the date of termination of the torque to the wheels to a complete stop.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
