If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.

The ratio of output compaired to in input?
It is the efficiency of a machine.
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
The ratio output power to input power in percent is called?
B. Efficiency
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
How does the output work compare to the input work for a machine that has an efficiency to less than 100 percent?
Then the output work is less than the input work. That description applies to every machine that has ever been built or will ever be built.
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
What do you mean by the efficiency of a simple machine is 85 percent?
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.

input
How does the output work compare to the input work for a machine that has an efficiency less than 100?
For a machine with efficiency less than 100%, the output work will always be less than the input work. This is because some of the input work is lost as waste energy due to factors like friction, heat, or other inefficiencies in the machine. The efficiency of a machine is a measure of how well it converts input work into useful output work.
Why would a machine with 100 percent efficiency be considered an ideal machine?
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
What is percent efficiency?
Percent efficiency is a measure of how well a system or process converts input resources into output results. It is calculated by dividing the actual output by the theoretical maximum output, then multiplying by 100 to express it as a percentage. A higher percent efficiency indicates a more effective use of resources in achieving desired outcomes.
What ratio of output work to input work expressed as a percent is the of a machine.?
The efficiency of a machine is a measure of the ratio of output work to input work, expressed as a percentage. It is calculated as: Efficiency = (Output Work / Input Work) x 100% A more efficient machine will have a higher percentage, indicating that a greater percentage of input work is being converted to useful output work.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
Can a machine have 110 percent efficiency?
No, a machine cannot have 110 percent efficiency. Efficiency is calculated as output divided by input, with 100 percent being the maximum achievable efficiency. Having a value higher than 100 percent would imply that the machine is producing more output than the input provided, which is not physically possible.
