The position of a material point is determined in relation to some other, arbitrarily chosen body, called a body of reference. A reference system is associated with it - a set of coordinate systems and clocks associated with the reference body. In the Cartesian system
Probably everyone has wondered about the efficiency (Coefficient of Efficiency) of an internal combustion engine. After all, the higher this indicator, the more efficiently the power unit operates. The most efficient type at the moment is considered to be the electric type.
The efficiency factor (efficiency) is a value that, as a percentage, expresses the efficiency of a particular mechanism (engine, system) in converting the received energy into useful work. Read in this article Why Efficiency
Electric motors appeared quite a long time ago, but great interest in them arose when they began to represent an alternative to internal combustion engines. Of particular interest is the issue of electric motor efficiency, which is one of its main characteristics.
Today we will tell you what efficiency (coefficient of performance) is, how to calculate it, and where this concept is applied. Man and mechanism What unites a washing machine and a cannery? A person’s desire to relieve himself of the need to do everything on his own
Efficiency, by definition, is the ratio of energy received to energy expended. If an engine burns gasoline and only a third of the resulting heat is converted into vehicle propulsion energy, then the efficiency is one third or (rounded to the nearest whole) 33%. If the light bulb
Efficiency (coefficient of performance) is the degree of efficiency of using fuel energy in the engine; the higher it is, the more thermal energy from the combustion of fuel is converted in the engine into mechanical energy of rotation of the main shaft. The less you waste
It is known that electrical energy is transmitted over long distances at voltages exceeding the level used by consumers. The use of transformers is necessary in order to convert voltages to the required values, increase the quality
Interaction of bodies. Experience shows that when bodies (or systems of bodies) come closer, the nature of their behavior changes. Since these changes are reciprocal, the bodies are said to interact with each other. When separating bodies over very long distances
Instructions During movement, a material body changes its position in space. Its trajectory can be a straight line or arbitrary; its length is the path of the body, but not the distance over which it has moved. These two quantities coincide only
