When a machine is 100% efficient, theoretical and actual MAs are the same.
Please let me know when you run across one of these.

What is more efficient an inclined plane or a lever?
Whichever has the greater Mechanical Advantage.
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.
What is the difference between real mechanical advantage and speed ratio?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
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.
What role does friction have in mechanical efficiency?
Nothing is 100% efficient because friction acts opposite on everything.
What is more efficient an inclined plane or a lever?
Whichever has the greater Mechanical Advantage.
The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency

What is your opinion Of the screw as a lifting device?
Even the best screws only have a mechanical advantage of twenty percent. Therefore, the screw is not a very efficient lifting device.

What reduces the mechanical advantage of a machine?
The mechanical advantage of something is related to the power input (fuel) and the power output (work) that the machine is given/gives out (respectively) I'm not entirely sure what means what (i.e. a mechanical advantage of over 1 or 3 or whatever = efficient, and such) Hope I helped. If you need to, I think the last place I saw a lesson on this was in a Holt physical science book, if you wanted to search for that lesson online or something.

What is the principal advantage of divinsion of labor?
It is efficient.
What is the principal advantage of division of labor?
It is efficient!
What is the advantage and disadvantage of privatization of waste management?
efficient
Can electrical energy change into mechanical energy?
Yes, and its one of the most efficient ways to get mechanical energy at 95%.
