The longer the effort arm of a lever, the less effort force is needed to lift a load. This is because a longer effort arm increases the leverage, allowing a small effort force to lift a greater load. Conversely, a shorter effort arm requires a greater effort force to lift the same load.
The length of effort and load in a project can be determined by estimating the amount of time or resources required to complete a task. This involves breaking down the project into smaller components, assigning resources to each task, and then estimating the time needed to complete each activity. By adding up the total time or resources required for all tasks, one can determine the overall length of effort and load for the project.
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
The formula to calculate effort force in a lever is Effort Force = Load Force x Load Arm Length / Effort Arm Length. This formula takes into account the load force being lifted, the length of the load arm, and the length of the effort arm to determine the amount of effort force needed to lift the load.
It is the part of a lever, where external force is applied in order to do work.
The IMA of a first-class lever can be increased by increasing the distance between the applied effort and the pivot point. This creates a longer lever arm, allowing for more torque to be produced with the same amount of force. Alternatively, decreasing the distance between the load and the pivot can also increase the IMA by reducing the effort required to lift the load.

The magnitude of the effort is controlled by you, not by the distance of the load from the fulcrum. Moving the load farther away from the fulcrum has no effect on the effort. But if you want to leave the effort where it is and still lift the load with the lever, then you're going to have to increase the effort.
The force you are referring to is called torque. here is an example: you have 2 wrenches, one with a short handle and the other with a long handle, and 2 identical bolts. The force required for the longer wrench to turn the bolt is less than the force required for the short to turn the bolt. This is because the longer the handle the greater the Torque and therefore less force needs to be applied. summary: longer "effort arm"=more torque= less force needed shorter "effort arm"=less torque=more force needed I hope this answers your question
The length of the lever arm and the placement of the fulcrum can affect how easy it is to use a lever. A longer lever arm provides more mechanical advantage, making it easier to lift or move objects. Positioning the fulcrum closer to the load can also make it easier to use a lever by reducing the effort required.
The equation for effort length typically refers to the distance over which a force is applied in the context of levers or mechanical systems. In simple terms, it can be expressed as the ratio of the lengths of the effort arm to the load arm, where effort length is the distance from the fulcrum to the point where the input force (effort) is applied. Mathematically, it can be represented as ( \text{Effort Length} = \frac{\text{Load Arm Length}}{\text{Mechanical Advantage}} ). This relationship helps in analyzing the efficiency and effectiveness of various machines and levers.
There is no short cut. Measure the length of each side and sum the lengths together. You may be lucky and the irregular polygon may have sides of the same length but different angles - and that will reduce the effort required..
The number of blades required is proportional to the amount of lift required. There are several factors that affect the amount of lift produced by rotor blades. They are the shape of the air foil, the rotational speed, the angle of attack, the length of the rotor blades, and the strength of the blades. All of these have practical limits. Adding an additional blade helps keep all these parameters within practical limits.
It is possible for some people to memorize the entire Bible, but it would require a significant amount of time, effort, and dedication due to its length and complexity.
