Efficiency is simply, the ratio of the output to the input of any system .That is, the amount of energy produced that is converted into work [Work =Force X Displacement] For example, a combustion engine produces alot of energy but mostly in the form of heat and noise.Only ~25% of the energy trapped in the hydrocarbon bonds is concverted from chemical to mechanical energy.Therefore, it has an efficiency of roughly 25%. So efficiency of machines is the actual work they do in relation to the total amount of power they produce.

Reduction of losses, such as those due to friction, makes a machine more efficient.

Efficiency is always less than 100% due to the friction. So therefore efficiency of a machine is always affected by a friction

It is defined as the ratio of the output of a machine to the input to the machine.

It is the output energy compared to the input energy. This will always be less than 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.

### 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 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 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.

### 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.
