What does conversion of electrical power to mechanical power mean?
There is no such thing as 'electrical power' or 'mechanical power' or, in fact, any other sort of power. Power is simply a rate -the rate of doing work. In SI, power is measured in watts. An obsolete unit of power is a horsepower. Although, in the Unites States, the power of an engine is usually measured in horsepower, elsewhere it is measured in watts (or, more usually, kilowatts).So, when an engineer describes converting electrical power to mechanical power, what he actually means is the rate of converting electrical energy to mechanical energy.
What is the power output of the human heart?
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
Where does the input power go when the mechanical output power is zero?
either to friction (heat, sound, light) or to internal mechanical changesAnother AnswerPower doesn't 'go' anywhere! Power is simply a 'rate': the rate at which the machine is doing work. If the machine isn't doing work by supplying a mechanical load, then it's output power is zero. However, energy still has to be provided to overcome the losses due to heat transfer from the machine, friction, windage, etc. The rate at which this energy is supplied to the motor is the power of the machine off load.
Is power the rate of which work is done?
In general, work is the rate at which energy is converted, or transferred. It may specifically refer to mechanical work, but it need not be that. For example, the amount of radiation radiated by the Sun can be measured in watts (a unit of power), but most of the energy emitted is unrelated to mechanical energy.
What are two quantities of power?
Two common quantities of power are electrical power and mechanical power. Electrical power, measured in watts (W), is the rate at which electrical energy is converted into another form of energy, such as heat or light, in devices like light bulbs or motors. Mechanical power, also measured in watts, refers to the rate at which work is done or energy is transferred in mechanical systems, such as engines or turbines. Both quantities are essential in various fields, including engineering and physics.
The relation between force mechincal and power electrical?
In electrical systems, power is the rate at which electrical energy is converted to other forms of energy, such as heat or mechanical work. Force is a component of mechanical power, representing the effort needed to move an object. In some cases, electrical power can be converted to mechanical power through devices like electric motors, where force is generated to do mechanical work.
Is it possible to amplify mechanical power?
Yes, it is possible to amplify mechanical power by preserving the input power.
Relation of power with work and time?
Power = energy / time"Energy" refers to transfer of energy, and it may specifically refer to work (which is the transfer of mechanical energy).
What is the efficiency of her body when a cyclist expends 1000 W of power to deliver mechanical energy to the bicycle at the rate of 100 W?
100/1000. 10 %
What is the application of generator and motors?
A generator converts mechanical power into electrical power. A motor converts electrical power into mechanical power.
