Deceasing friction increases efficiency and reduces heat loss.
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
Then the machine would have a greater output power, or alternately, require less input power.
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.
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.

Generally automobiles are designed with optimum size wheels. Changing the diameter is unlikely to increase efficiency, and could well have the opposite effect.
The energy efficiency increases as the angle increases.
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 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.
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 is 80%. To find the efficiency, 400/500 = 80%.
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 ?
no machine has one
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.
