Solution of problem D3 (task 1) Option 15 Dievsky V.A.

Termeh Dievsky V.A. proposes in task Dynamics 3 (D3) task 1 to consider the mechanical systems shown in diagrams 1-30. Using the theorem on the change in kinetic energy in differential form, it is necessary to determine the angular acceleration (options 4, 6, 7, 9, 11, 18, 25, 26, 28) or linear acceleration (other options) of body 1. The threads in the systems are considered weightless and inextensible. The following notations are used in the problem: m - body masses, R and r - radii, p - radius of inertia (if it is not specified, the body is considered a homogeneous cylinder); in the presence of friction, f is the sliding friction coefficient, fк is the rolling friction coefficient.

To solve task 1 of problem D3 in diagram No. 15, it is necessary to use the theorem on the change in kinetic energy in differential form. The linear acceleration of body 1 should be determined. The threads are considered weightless and inextensible. Designations: m1 - mass of body 1, m2 - mass of body 2, R - radius of the wheel, r - radius of the cylinder, f - coefficient of sliding friction.

The digital goods store presents a solution to problem D3 (task 1) Option 15 from the author Termekh Dievsky V.A. This digital product is intended for students and teachers studying the dynamics of mechanical systems. The solution to the problem is carried out in accordance with the theorem on the change in kinetic energy in differential form and contains the definition of the linear acceleration of body 1. The problem uses threads that are considered weightless and inextensible, and also indicates the masses of the bodies, the radii of the wheels and cylinders, as well as the sliding friction coefficient. The solution to the problem is presented in a beautiful html design, which makes it easy to read and use. This digital product is an indispensable assistant for those who study the dynamics of mechanical systems and are looking for a proven and high-quality solution to the problem.
