There is no such thing as the 'rate of mechanical power', because power itself is a rate. There's also no such thing as 'mechanical' power as power is a rate, not something that is tangible.

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 factors affect the rate of mechanical weathering?
factors that affect the rate of mechanical weathering?
Is it possible to amplify mechanical power?
Yes, it is possible to amplify mechanical power by preserving the input power.
What is the application of generator and motors?
A generator converts mechanical power into electrical power. A motor converts electrical power into mechanical 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 %
When a cyclist expends 1000 watts of power to deliver mechanical energy to her bicycle at a rate of 100 watts what is the efficiency of her body?
Divide the useful power by the total power spent. Then - if you want a percentage - multiply the result by 100.
What is the relationship of work Energy and power?
Work is the transfer of mechanical energy; its units are the same as for energy, for example joule. Power is the rate of transfer of energy, and it has units of energy/time, for example watt.
