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 .
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.

Explain how much efficiency of an ideal machine compares with the efficiency of a real machine?
An ideal machine has, by definition, an efficiency of exactly 100%, which means that absolutely none of the energy it consumes is wasted when converted to power (energy per unit of time), hence the name "ideal". A real machine, however, will never reach an efficiency of 100%, as there will always be at least a tiny bit of energy that is lost to the environment. This is because it is practically impossible to create a perfectly closed system in which no energy can leak out. It is possible, however, to build very efficient systems and machines, although this depends on just how well they are made. Therefore, the efficiency of a real machine is quite variable, going easily from 10% to 98%, depending on its quality. A simple example is that of ordinary household voltage transformers, which generally have efficiencies of around 80%; and of high grade power plant transformers, which have efficiencies of around 98%.
How is a real machine like an ideal machine?
A real machine is like an ideal machine in that there are no massless chains or frictionless bearings. The parts of an ideal machine are rigid and weightless.
Work input equals work output is what type of machine?
Such as machine is said to have an efficiency of 100%. Since some type of energy loss is unavoidable, this is not possible in real life, but in some cases it can be approximated quite well.
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
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.
What is an obstacle to 100 efficiency for a real machine?
Friction.
Why do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?
Such a machine would have an efficiency of 100% and, as the question suggests, it would be a miracle. No real machine is 100% efficient because there are always losses.
