Solution of problem D3 (task 1) Option 20 Dievsky V.A.

Termeh Dievsky V.A. proposes in the Dynamics 3 (D3) task 1 to consider the mechanical systems depicted in diagrams 1-30, and using the theorem on the change in kinetic energy in differential form, determine the angular acceleration (options 4, 6, 7, 9, 11, 18, 25 , 26, 28) or linear acceleration (in other variants) of body 1. The task indicates that the threads are weightless and inextensible, and also provides the following designations: m - body masses, R and r - radii, p - radius of inertia (if it is not indicated, 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 for scheme No. 20, it is necessary to use the theorem on the change in kinetic energy in differential form and determine the linear acceleration of body 1. It should also be taken into account that the thread is weightless and inextensible. To solve the problem, you need to know the mass of the body, radius and coefficient of friction, if any.

This digital product is a solution to problem D3 (task 1) Option 20, created by Termekh Dievsky V.A. This product is sure to be useful for students taking a course in dynamics, as well as for anyone interested in mechanics. The solution to the problem is accompanied by a beautiful html design, which makes it convenient and attractive to read. You can easily download this product and use it as a sample for solving similar problems or as exam preparation material. With this product, you can easily understand how to apply the kinetic energy theorem in differential form to determine the linear acceleration of a body 1.
