A simple machine requires this in order to operate?
The mechanical advantage of a compound machine is the multiple of the separate mechanical advantages of each simple machine. The efficiency of the compound machine is also the multiple of the separate efficiencies of each simple machine. So the work in to the first machine multiplied by all of the simple machine efficiencies gives you the work out of the last machine
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?

If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
please rephrase ur question so that it can be understood
How is a real machine and an ideal machine different?
An ideal machine can reach 100% efficiency as there is no friction or other restraints involved, whereas a real machine can never reach 100% efficiency.
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.
What is efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
If the output work of a simple machine equals the input work the machine is said to have efficiency.?
In that case, the efficiency is said to be 1 - or equivalently, 100%.
What are some simple ways to improve your car's fuel efficiency?
Some simple ways to improve your cars fuel efficiency are to make sure your tires are at the proper pressure, that your air filter is clean and that you change your oil and spark plugs at regular intervals.

The ratio of output force to input force for a simple machine is called its advantage?
The answer is mechanical advantage, not efficiency!
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
How do lubricants help to improve a machine's efficieny?
Lubricants help to improve the efficiency of a machine by allowing for a lessening of friction between moving parts. This causes those parts to remain cooler and have less wear and tear in the long run.
Explain efficiency and how to calculate it for different simple machines?
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What type of efficiency would a simple machine have if the output work of the machine equals the input work?
Although it is impossible for any machine to have an efficiency of 100%, it would in this case be 100%. Studies have shown that when ever there is motion, there has to be a loss of energy due to friction. So any rotating machine, big or small will have losses.
