In this paper we consider the controlled differential inclusion with a delay argument. For such models of dynamical systems, the Cauchy problem is studied. Some properties of the set of solutions and the ensemble of trajectories of the considered class of differential inclusions are studied. Conditions for continuous dependence and convexity of multivalued mappings related to the studied properties of solution of differential inclusions are obtained

It should be noted that the approximate solution of Newton's differential equation helps the student to form initial skills and ideas, but does not cover all computer methods for solving Newton's equation. The article selected the simplest possible mechanical problems and tried to choose the simplest algorithms for its approximate solution. Common languages such as EXEL, BASIC, PASCAL can be used for programming the algorithm. It is known that modern MATLAB (Simulink), MAPLE (PDE_Solve) systems have ready packages for approximate solution of differential equations. However, this article will help the reader to understand their main essence.

The process of removing cotton from the spindle as it moves in the removal area of the harvesting apparatus is examined in the article. The doffers, which are one of the components of the harvesting apparatus, perform a complete removal of cotton from the spindles, clean the surface of the spindle from individual fibers and cotton leaves, and ensure a continuous supply of raw cotton removed from the spindles into the receiving chamber for its further transportation to the hopper of the cotton harvester. A computational scheme for the spindle motion in the removal zone was developed and, on its basis, the path of the points lying at the ends of the doffer brushes, and the shapes of the curves enveloping these paths, were determined. These curves can be considered the boundaries of the zone of direct interaction of the doffer with a skein of cotton on the spindle. Based on modeling the process of interaction of the cotton-carrying spindle with the doffer in the removal zone of the harvesting apparatus, a calculation formula was obtained to determine the boundary of the zone of effect of the doffer brushes on a skein of cotton wound on the spindle; numerical calculations were conducted in the MathCAD 15 programming environment. The calculation results showed that with an increase in the angular velocity of spindle rotation, the boundary of the zone of effect of the doffer brushes is significantly closer to the spindle circle, which leads to a complete removal of cotton.
