How efficient is a machine that outputs 67J when 150J of work are input?

The efficiency of the machine can be calculated using the formula efficiency = (useful output / total input) * 100%. In this case, the efficiency of the machine would be (67J / 150J) * 100% = 44.7%. This means that the machine is operating at 44.7% efficiency in converting input work to useful output.


What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?

The efficiency is 80%. To find the efficiency, 400/500 = 80%.


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


How is a machine's efficiency of a calculated?

Efficiency = useful output power / input power


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.)


What is the mechanical efficiency of a machine whose work input is 100 J and work out put is 30 J?

The mechanical efficiency can be calculated using the formula: Efficiency = (Work output / Work input) * 100%. Given the values, we have: Efficiency = (30 J / 100 J) * 100% = 30%. Therefore, the mechanical efficiency of the machine is 30%.


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).


What is a specific example of a machine and describe how its mechanical efficiency might be calculated?

An example of a machine is a car engine. Mechanical efficiency can be calculated by comparing the work output (such as the power produced by the engine) to the work input (such as the energy from the fuel). The formula for mechanical efficiency is: Efficiency = (useful work output / total work input) x 100%.


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).


The efficiency of a machine is usually expressed in?

The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.


How can a machine's efficiency be calculated?

Machine efficiency can be calculated by dividing the useful output of the machine by its total input, and then multiplying by 100 to express it as a percentage. Useful output could be output energy, work done, or products manufactured, while total input includes energy or fuel consumed. The formula for efficiency is: Efficiency = (Output/Input) x 100%.
