What is the ideal and actual mechanical advantage of a machine?
we can save our time by using machines and a machine can perform the work of hundred men.
Does an ideal machine have friction?
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
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.
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.
What is the difference between actual machanical advantage and ideal machanical advantage?
Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.

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 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.
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.

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.
If a machine was 100 percent efficient how would the AMA compare to the IMA?
At perfect 100% efficiency, the Actual Mechanical Advantage should equal the Ideal Mechanical Advantage.
Why is the actual mechanics advantage of a machine always less than it ideal mechanical advantage?
Because the "ideal advantage" doesn't always consider all factors i.e. gravity, friction, heat/cold etc. It considers just the "ideals".
