If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.
Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?
The machine efficiency is 35 percent (35/100).
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
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%.
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Efficiency % = (work out / work in) * 100 (Work = force * distance)
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.
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
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.
