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.
If a machine's input work and output work are equal the machine has high?
It has 100% efficiency, and one might say that the machine has replaced friction with fiction.
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
What is an obstacle to 100 efficiency for a real machine?
Friction.

How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
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.

What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
Can a machine's efficiency can be greater than 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.
Can any pulley have a efficiency over 100?
No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.
What is an obstacle to 100 efficiency for a real machine?
Friction.
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
What is efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
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.
