Problem 20.5.11 from the collection of Kepe O.?. is formulated as follows:

Given: kinetic energy of the disk, expressed in terms of generalized speed - T = 12?^2; moment of a pair of forces acting on the disk - M = 6 N·m. Required to find: angular acceleration of the disk.

Solution: The kinetic energy of the disk can be expressed in terms of the moment of inertia I and the angular velocity ω: T = Iω^2. Since the generalized speed is related to the angular speed by the relation ?, we can write: T = 12(I?^2).

The moment of force is related to the angular acceleration α by the following relationship: M = Iα, where I is the moment of inertia of the disk. Since the moment of inertia of the disk is unknown, but it can be expressed through the generalized speed and angular acceleration, we can rewrite the formula for the moment of force: M = 12(?α?^2).

It is necessary to find the angular acceleration of the disk, so we solve the equation for α: α = M/(12?^2).

Substituting the known values, we get: α = 6/(12*?^2) = 0.25 (rad/s^2).

Answer: the angular acceleration of the disk is 0.25 rad/s^2.
