How does the work done a machine compare to the work done by a machine?
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
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.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into 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.
What must you know in order to calculate a machine's efficiency?
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
How can convert efficiency to percent?
Work done = (force * distance)>Efficiency (%) = (Work done output / Work done input) * 100
How much will a car be worth after 5 years if you buy it for 20000 and the value decreases by 10 percent year?
20000 - 20000(.10)(5) = $10000 **That is assuming there was no real damage done!

How do you determine machine efficiency?
Machine efficiency is typically determined by calculating the ratio of useful output to input. This can be done by comparing the actual output of the machine to its theoretical maximum output under ideal conditions. Factors such as energy losses, downtime, and maintenance can also affect machine efficiency.
Formula to calculate work efficiency?
efficiency formula is (Wout/Win)*100% Wout is the work done by the machine is called the output work Win is the work done by you on a machine is called the input work efficiency= useful work output/work input For science, the effiency is: AMA/IMA * 100
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
Efficiency is a measure of power losses. A machine with an efficiency of say 85% or 0.85, experiences 15% power losses from input to output (as heat through friction) This would be typical for say a car, comparing crankshaft power to power at the drive wheels. No machine will exceed 100% efficiency > Work done = force * distance Efficiency = work done at output / work done at input > Mechanical Advantage (leverage) is distance moved by input / distance moved by output. Output force = input force * Mechanical Advantage
How is the efficiency of a compound machine calculated?
The efficiency of a compound machine is calculated by dividing the output work of the machine by the input work. Mathematically, it can be expressed as Efficiency = (Output work / Input work) * 100%. It gives a measure of how well the machine converts input work into useful output work.
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
