A longer lever would typically have more mechanical advantage than a shorter lever. Mechanical advantage is calculated by dividing the length of the effort arm by the length of the resistance arm; therefore, the longer the effort arm, the greater the mechanical advantage.
A lever operating at a mechanical advantage allows you to apply less force to lift or move a heavier object. This makes it easier to perform tasks that would otherwise require more strength.
Changing the fulcrum position of a lever can affect the mechanical advantage by changing the ratio of the lever arms on either side of the fulcrum. Moving the fulcrum closer to the load will increase the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force will decrease the mechanical advantage, requiring more effort to lift the load.
A lever with a resistance arm of 3 inches and an effort arm of 1 inch would have more mechanical advantage as the effort arm is shorter than the resistance arm, making it easier to lift the load.
In a first class lever, as the distance from the fulcrum to the point where the input force is applied increases, the mechanical advantage also increases. This means that the lever becomes more efficient at moving a load with less effort.
A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.

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
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.
A lever uses its mechanical advantage by allowing a small force to lift a larger load by increasing the distance over which the force is applied. This is achieved by positioning the fulcrum closer to the load and farther from the effort force, distributing the work more efficiently.
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 '
The advantage of a first class lever is that by using less input force, you get more output force. Teehee!
The resistance force on a lever opposes the effort force applied to the lever, making it more difficult to move or lift an object. The resistance force helps balance the lever and determine the resulting mechanical advantage.
One limitation of a lever is that the length of the lever arm can affect its mechanical advantage, meaning that longer lever arms can provide more force but require more effort to move. Additionally, friction between the lever and the fulcrum can reduce the efficiency of the system.
