Task 10743.
The disk radius of 10 cm and a weight of 2 kg is rotated around its axis extending perpendicularly to the plane through the center of the radius. The law of motion drive f = 6 + 4t-t2 (rad). Determine the moment of force acting on the disc, and the kinetic energy of the disk 2 seconds after the start of the rotation of the disc. Plot the points of force and torque from the drive pulse time.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
