Task 10427.
The flywheel has a disk shape with a diameter of 40 cm and a weight of 100 kg; it rotates with a frequency of 10 / c. The flywheel is stopped by the brake pads, which clinging to its rim, creates a friction force of 60 N. Find: 1. The moment of friction forces 2. The moment of inertia of the flywheel 3. The angular acceleration during deceleration (in absolute value) 4. How much time will stop the flywheel?
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
