What is the difference between a ideal machine and real machine?

In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .


Does an ideal machine would have an efficiency greater than one?

No, an efficiency greater than one would not be possible, since that would violate a very fundamental law of physics: conservation of energy. The efficiency of an "ideal machine" would be one, in many cases; the efficiency of an ideal Carnot engine would be less than one.

How the efficiency of a ideal machine compares with the efficiency of a real machine?

In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!


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.


Does an ideal machine have an effciency of 100 percent?

No, there is not such thing as an ideal machine; it's just an idea.


What would a machine that had 100 percent mechanical efficiency be called?

an ideal machine


The efficiency of a real machine?

Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.


In what machine does work input equals work output?

In practical there is no machine which have efficiency 100%,i.e. output work = input work. But an ideal machine have efficiency of 100%, for an example a Carnot's heat engine. The efficiency of this engine is 100% but it is an ideal situation. As an expression of efficiency it is equal to W/Q, where W is work done by the system and Q is heat put into the system. For efficiency =1 ,i.e.100% if and only if W=Q and vice verse.

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.


An ideal machine would have an efficiency of?

A ideal machine would have an efficiency of 100 percent. For this to be possible, the amount of energy output by the machine would equal the amount of energy input. Because all machines have physical parts, some energy is lost to friction, heat dissipation, or other factors, so no machine can be an ideal machine.
