Solution to problem 13.3.15 from the collection of Kepe O.E.

13.3.15. Consider a horizontal disk with a vertical axis of rotation and a body located at a distance of 2 m from this axis. It is necessary to find the angular velocity of uniform rotation of the disk at which the body begins to slide along the disk with a sliding friction coefficient f = 0.3. The answer is the angular velocity value is 1.21.

I'll add a little explanation. In order for the body not to start sliding on the disk, it is necessary that the friction force between the disk and the body be large enough to overcome the inertia force of the body. The sliding friction coefficient f = 0.3 means that to achieve this condition it is necessary that the angular velocity of the disk be 1.21 rad/s (rounded to two digits).

The product is the solution to problem 13.3.15 from the collection of Kepe O.?. The task is to determine the angular velocity of uniform rotation of a horizontal disk at which a body located at a distance of 2 m from the vertical axis of rotation begins to slide along the disk. The sliding friction coefficient between the body and the disk is 0.3.

To solve the problem, it is necessary to find the angular speed of rotation of the disk at which the sliding friction force will be equal to the force of the centrifugal force acting on the body. In this case, the body will stop moving in a circle and begin to slide along the disk.

Solving the problem comes down to finding the angle of inclination of the tangent to the trajectory of the body on the disk. This angle can be expressed in terms of the angular speed of rotation of the disk and the distance from the body to the center of rotation. Then, using the laws of dynamics, it is possible to express the force of sliding friction in terms of the angular velocity of rotation of the disk and the mass of the body. By equating this sliding friction force to the centrifugal force, we can find the angular speed of rotation of the disk at which the body begins to slide.

The answer to the problem is 1.21.
