What is more efficient an inclined plane or a lever?
Whichever has the greater Mechanical Advantage.
What are the levers that operate at a mechanical advantage?
Every lever has a mechanical advantage. It may be less than ' 1 ' ... the outputforce may be less than the input force ... but it can always be calculated.The 'ideal' mechanical advantage ... that is, in the absence of losses ... isClass I lever . . . . . any number, depending on dimensions of the structureClass II lever. . . . . more than 1Class III lever.. . . . less than 1
How would you set up a lever so that it has a mechanical advantage greater than 1?
Move the fulcrum point so it is more than halfway toward the object being moved.
What lever would have more mechanical advantage than one with a resistance are of 3 inches and an effort arm of 6 inches?
increase the effort arm to 8 feet
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum

What is the mechanical advantage of a lever with a load of 100n and an effort force of 10n?
You haven't mentioned whether the effort force of 10n is successfully lifting the load of 100n. If it is, then the mechanical advantage of the lever is 10 or more. If the load is just sitting there and not lifting, then the MA of the lever is less than 10. Note: None of this analysis has any value unless the lever itself is massless.
How is machanical advantage calculated for a third class lever?
Mechanical advantage: Class-I lever . . . can be any positive number Class-II lever . . . always less than ' 1 ' (and more than zero) Class-III lever . . . always more than ' 1 '
What does the mechanical advantage of a first-class lever depend upon?
The advantage of a first class lever is that by using less input force, you get more output force. Teehee!
How would you set up a lever so that it has a mechanical advantage greater than 1?
Move the fulcrum point so it is more than halfway toward the object being moved.
Is it true a simple machine is one that always gives a mechanical advantage of 2?
No. A simple machine such as a lever could quite easily give a mechanical advantage of 10, 100 or more, or could even be less than 1.
To increase the mechanical advantage of a lever you should?
Easy. The longer the lever is (or the further out you hold it) the more torque you will be able to apply (T = F x r). Also, by pulling the lever perpendicular to it's axis of rotation, no energy will be wasted as it would if you were pulling it to one side or the other against or away from the pivot.

Is a toothbrush a simple machine?
I wouldn't call it that. It's more like a lever. You hold one end of the toothbrush and the other end of the lever is the bristled working end against the teeth and gums. As the fulcrum is on the working end, there is no mechanical advantage for the toothbrush lever.
What is the advantage of adding pulleys to a pulley system?
More mechanical advantage.
