Task 00140.
The cylindrical body is rigidly fixed on the horizontal axis of radius r = 8 mm. A cord is wound around the axle, to the end of which a load of mass m = 2.0 kg is attached. The system is brought into rotation from a state of rest under the action of a descending load. Determine the moment of inertia of the body if the load falls over a distance h = 1 m during t = 12 s. The friction force can be neglected.
Detailed solution with a brief record of the conditions, formulas and laws used in the decision, the conclusion of the calculation formula and the answer.
