Mechanical advantage of a 3rd class lever?
always less than 1
The mechanical advantage of a second class lever?
... is always less than 1 .
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's 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

What is the mechanical advantage of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
What is the Mechanical Advantage of levers?
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.

Is it possible for a first or second class lever to have a mechanical advantage less than one or for a third class lever to have a mechanical advantage greater than one?
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
What is a lever with a mechanical advantage greater than one used to do?
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
