How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
If the input work on a machine is equal to its output work does the machine has efficiency?
If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Why does a high-efficiency machine is more desirable than low-efficiency machine?
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.
What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
What is the formula for efficiency of a machine?
useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
How is the efficiency of a compound machine calculated?

What is the relationship between an input work and useful output work?
The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.
The comparison between output work imput work is?
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
Can you get more energy out of fuels if you increase the percentage of energy used for work?
The percentage of energy converted into useful work is called the EFFICIENCY.
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
