It is the part of a lever, where external force is applied in order to do work.

What kind of lever has a fulcrum resistance arm and effort arm?
A Class 2 lever has the fulcrum located at one end, with the resistance/load in the middle and the effort applied at the other end. The effort arm is shorter than the resistance arm in a Class 2 lever.
What is the force advantage for levers?
The force advantage for levers is the factor by which a lever multiplies the input force applied to it. This advantage is determined by the ratio of the distances from the fulcrum to the point where the input force is applied (effort arm) and the point where the output force is exerted (load arm). The longer the effort arm compared to the load arm, the greater the force advantage.
Basis for the classification of lever?
The classification of levers is based on the relative positions of the effort, load, and fulcrum. There are three types of levers: first-class levers have the fulcrum placed between the effort and load, second-class levers have the load between the fulcrum and effort, and third-class levers have the effort between the fulcrum and load.
How is mechanical advantage calculated for levers?
The mechanical advantage of a lever is calculated by dividing the length of the lever arm on the effort side by the length of the lever arm on the resistance side. The formula for mechanical advantage is MA = Length of effort arm / Length of resistance arm. It represents the factor by which a lever multiplies the force applied to it.
What are the disadvantages of second class levers?
Some disadvantages of second-class levers include that they require a lot of force to move the load as the effort arm is shorter than the resistance arm. They also tend to have limited range of motion compared to first-class levers and are less common in nature and technology.
What kind of lever has a fulcrum resistance arm and effort arm?
A Class 2 lever has the fulcrum located at one end, with the resistance/load in the middle and the effort applied at the other end. The effort arm is shorter than the resistance arm in a Class 2 lever.

What levers are in the arm?
3rd class levers are in your arm.
Basis for the classification of lever?
The classification of levers is based on the relative positions of the effort, load, and fulcrum. There are three types of levers: first-class levers have the fulcrum placed between the effort and load, second-class levers have the load between the fulcrum and effort, and third-class levers have the effort between the fulcrum and load.
What is the equation for effort length?
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.
Why is the mechanical advantage of second class levers is always greater than 1?
Because the load is always between the effort and the fulcrum, so the effort arm is always longer than the load arm.
What class of lever is a radio?
Since a radio has no effort arm, no load arm, and no fulcrum, it's quite difficult to include it in the category of "levers", of any class.
How do levers provide mechanical advantage?
Levers provide mechanical advantage by allowing a smaller input force to lift a larger load through the principle of torque. By positioning the fulcrum closer to the load, the effort arm (distance from the fulcrum to the point of applied force) is lengthened, enabling the user to exert less effort to move the load. This mechanical advantage is quantified by the ratio of the lengths of the effort arm to the load arm. Consequently, levers make it easier to perform tasks that would otherwise require more force.
How is mechanical advantage calculated for levers?
The mechanical advantage of a lever is calculated by dividing the length of the lever arm on the effort side by the length of the lever arm on the resistance side. The formula for mechanical advantage is MA = Length of effort arm / Length of resistance arm. It represents the factor by which a lever multiplies the force applied to it.

A is a simple machine with a fulcrum an effort arm and a resistance arm?
A is a lever, a type of simple machine. The fulcrum is the point where the lever pivots, the effort arm is where the input force is applied, and the resistance arm is where the output force is found. Levers are used to amplify the input force to overcome a resistance.
How are levers grouped into classes?
Levers are grouped into three classes based on the relative positions of the load, effort, and fulcrum. Class 1 levers have the fulcrum between the load and the effort. Class 2 levers have the load between the fulcrum and the effort. Class 3 levers have the effort between the fulcrum and the load.
