Problem 18.3.2 from the collection of Kepe O.?. consists in determining the moment of a pair of forces necessary to uniformly lift a load weighing 200 N on a drum of radius 20 cm. To solve the problem, it is necessary to use the laws of mechanics and the principles of equilibrium of bodies.

The moment of force is defined as the product of force and the distance to the axis of rotation. In this case, the axis of rotation is a drum with a radius of 20 cm. To lift the load onto the drum, a pair of forces must be applied, consisting of the gravity of the load and the force necessary to overcome the friction force between the load and the drum.

Using the principle of equilibrium of bodies, we can write the equation for moments of forces:

Mg - Mtr = 0,

where Mg is the moment of gravity of the load, Mtr is the moment of friction.

The moment of gravity is defined as the product of the weight of the load and the distance from the center of the drum to the point of application of gravity, that is

Мг = Fг * r,

where Fg is the weight of the load, r is the radius of the drum.

The moment of friction force is defined as the product of the friction force and the radius of the drum, that is

Mtr = Ftr * r,

where Ftr is the friction force.

Thus, in order to find the moment of a pair of forces necessary to lift a load, it is necessary to calculate the friction force using the law of sliding friction and the equilibrium equation of bodies. The solution to the problem is the value of the moment of the pair of forces equal to 20.
