it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.
Nothing can be more that 100% (one hundred percent)! When people say that something is one hundred and ten percent - they are wrong. It is an attempt to imply that something is greater that it should be. It is similar to the annoying habit of adding !!!! at the end of a sentence, when a single ! is correct.
Electric induction motors typically have an efficiency of over 95 percent. These motors are commonly used in various applications such as industrial machinery, appliances, and electric vehicles due to their high efficiency in converting electrical energy into mechanical energy.
It is impossible to achieve 100 percent efficiency due to various factors such as friction, heat loss, and energy conversion losses. These factors result in some amount of energy being wasted in any process, making perfect efficiency unattainable.
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.
Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.
nothing has 100% efficiency.

The laws of thermodynamics imply that there will always be some loss of efficiency.
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
It is not a good efficiency engine.
Efficiency is normally written as a percentage, and does not have an SI unit."percent". It has no units.
No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.
It is not a good efficiency engine.
B.) efficiency
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.
why is the efficiency of a calorimeter less than 100%
