Задача 10508.

A rod with a mass of 6 kg and a length of 40 cm rotates around an axis passing through its middle, perpendicular to the length of the rod. The angle of rotation of the rod changes in time according to the law phi = 3t^3-t^2 4t 6. Determine the torque acting on the rod 2 s after the start of rotation.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
