The efficiency of a machine is a measure of how well it converts input energy into useful work output. It is calculated as the ratio of useful work output to the total input energy or power. A high efficiency indicates that the machine is able to minimize energy losses and perform its intended function effectively.

What increases as efficiency of a machine increases?
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
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.
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.
If the input work on a machine the machine has blank efficiency?
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
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%.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
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.
Describe why a high-efficiency machine is more desirable thana 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 is a machine with efficiency of less than one?
no machine has one
What is the efficiency of the machine?
a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?
What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
What is the machine efficiency of a machine that produces 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What increases as efficiency of a machine increases?
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
What limits the efficiency of machine?
friction
Why were machine guns used?

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.
