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!
A lever with a mechanical advantage greater than one is used to amplify the input force applied to it. This allows for easier lifting of heavy objects, moving loads with greater ease, or multiplying the force exerted by the user.
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.
Yes, that's correct. Mechanical advantage is calculated by dividing the output force by the input force. If the output force is greater than the input force, the mechanical advantage will be less than one, indicating that the machine trades off force for distance.

A thick wedge has a greater mechanical advantage than a thin wedge. The mechanical advantage of a wedge is calculated by dividing the length of the slope by the thickness of the wedge. Therefore, a thicker wedge will have a larger mechanical advantage since it has a longer slope relative to its thickness.
Speed ratio and mechanical advantage are not the same because they are inversely related. Speed ratio is a measure of how much the input speed is amplified or reduced by a machine, while mechanical advantage is a measure of how much the input force is amplified or reduced. A machine that increases speed will have a mechanical advantage less than one, while a machine that increases force will 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.
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.
No, a simple inclined plane always has a mechanical advantage of greater than or equal to 1. It reduces the force needed to lift an object by increasing the distance over which the force is applied. The mechanical advantage is calculated by dividing the length of the inclined plane by the height.
