The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
Mechanical work is the amount of energy transferred when a force acts on an object to move it over a distance. The connection between mechanical work is that the work done is equal to the force applied multiplied by the distance moved in the direction of the force, expressed mathematically as W = F*d.
Line segments are portions of a line that have two endpoints, making them finite in length. Unlike lines, which extend infinitely in both directions, line segments can be measured and have a specific distance between their endpoints. They can be described using coordinates in a Cartesian plane, and their properties are fundamental in geometry, including concepts like distance, midpoint, and slope.
Increasing the distance between the pivot point and the effort force, or decreasing the distance between the pivot point and the load, could increase the mechanical advantage of a second-class lever. Additionally, using a longer lever arm can also increase the mechanical advantage.
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.
They both are made of lines, but a line segment is only a certain distance while a line ever ends.
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.
In mechanical systems, the moment arm and lever arm both refer to the distance between the axis of rotation and the point where a force is applied. The moment arm specifically relates to the perpendicular distance, while the lever arm is the actual distance along the line of action of the force.

There are about 30 segments between the prostomium and clitellum of an earthworm. actually this question asked as differently as "How many segments are between the prostomium and clitellum of an earthworm?" see answer for this question.
Equal divisions between two fixed points refer to dividing the distance between the two points into equal segments. This can be achieved by dividing the total distance by the number of desired divisions. Each division would then have an equal length.
You can set up a lever system by increasing the distance between the applied force and the fulcrum compared to the distance between the fulcrum and the load. This configuration helps to amplify the force applied. The longer the distance between the force and the fulcrum, the greater the mechanical advantage.
