The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
The mechanical advantage of an inclined plane is equal to length divided by height (l/h). Therefore, if the length is less than than the height, the mechanical advantage would be less than one.
A mechanical advantage greater than one means that you have to put less effort into the system than if you had to do the work directly. Usually this is by spreading the effort you put in out over a longer distance or time. For instance, although in the end the same amount of work is done, lifting a box straight up with you hands is more difficult than using an inclined plane or lever to do the work.
Mechanical advantage is not the only reason to use levers.
If an IMA (ideal mechanical advantage) is less than one, that means the lever the force is applied to is shorter than the lever lifting the load.
numbers greater than one!
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.
it means the mechanical advantage is greater.
it means the mechanical advantage is greater.
A lever with a mechanical advantage greater than one is used to increase distance. A lever is a simple machine connected to ground by a hinge called a fulcrum.
increase distance.
lever, gear train
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.
The mechanical advantage of an inclined plane is the ratio of its length to the height of its lift. At 45 degrees, this ratio is equal to one. Less than 45 degrees and it is greater than one, more than 45 degrees, and it it less than one. So the answer is yes.

The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
