Can a inclined plane have a mechanical advantage of less than 1?
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.
What does a mechanical advantage greater than one usually mean?
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.
Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
What does it mean when the IMA is less than 1.0?
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.
A 1-cm screw with a 4-cm thread would have a mechanical advantage of?

What is a lever with a mechanical advantage greater than one used to do?
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.
If the input force is less than the input force of a simple machine the mechanical advantage is less than one?
it means the mechanical advantage is greater.
If the output force is less than the input force of a simple machine the mechanical advantage less than one?
it means the mechanical advantage is greater.
A lever with a mechanical advantage greater than one is used to do what?
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.
What A lever with mechanical advantage greater than one is used to?
increase distance.
If the output is greater than the input force of a simple machine the mechanical advantage is less than one?
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.
What two things provide a mechanical advantage greater than one?
lever, gear train
Which one has the greater mechanical advantage a thick wedge or a thin wedge?
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.
Why are speed ratio and mechanical advantage never the same?
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.
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.
Can a simple inclined plane have a mechanical advantage less than one?
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.
Can't a simple inclined plane have a mechanical advantage less than one?
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.
