Today we will tell you what efficiency is (coefficient of performance), how to calculate it, and where this concept is applied
When solving problems of moving objects, in some cases their spatial dimensions are neglected, introducing the concept of a material point. For another type of problems, in which bodies at rest or rotating bodies are considered, it is important to know their parameters and the points of application of external forces. In this case, we are talking about the moment of forces about the axis of rotation. We will consider this issue in the article
