40/10 = 4
Mechanical advantage=load/effort
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
load arm, effort arm, load, effort, fulcrum!
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
answer is 4
The mechanical advantage of a first-class lever depends on the relative distances between the effort force, the fulcrum, and the resistance force. The mechanical advantage is calculated as the ratio of the distance from the fulcrum to the effort force to the distance from the fulcrum to the resistance force.
The position of the fulcrum affects the mechanical advantage by changing the ratio of the input force to the output force. Moving the fulcrum closer to the load increases the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force decreases the mechanical advantage, requiring more effort to lift the load.
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.
As you move the effort force closer to the fulcrum, the mechanical advantage decreases. This is because the input force is applied over a shorter lever arm, which reduces the moment arms on both sides of the fulcrum, resulting in a smaller mechanical advantage.
It's the ratio of the distances effort-fulcrum/load-fulcrum.
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.
Increasing the distance between the effort force and the fulcrum or decreasing the distance between the resistance force and the fulcrum would increase the mechanical advantage of a first-class lever.
A mechanical advantage is increased in a 1st class lever when the distance from the fulcrum to the point of effort is greater than the distance from the fulcrum to the point of resistance. This allows for less effort to be exerted to move a greater resistance.
The mechanical advantage of a lever is determined by dividing the length of the lever on the effort side (distance from the fulcrum to the point where the effort is applied) by the length on the resistance side (distance from the fulcrum to the point where the resistance is located). This ratio provides insight into how much force is gained or lost when using the lever.
