Thank you very much, Ms Sue.
Please for a diagram to show the following.

You can find the other terms the same way I found that.

The study of levers is part of the broader field of mechanics and involves understanding the principles behind how these simple machines work. To explain some terms associated with the study of levers, let's begin with the basic definition and components of a lever:
1. Lever: A lever is a rigid bar or beam that is capable of rotating around a fixed point called the fulcrum. It is used to transmit and amplify mechanical force or motion.
2. Fulcrum: The fulcrum is the fixed point around which a lever rotates or pivots. It acts as a support or hinge for the lever.
3. Load: The load refers to the weight or resistance being lifted, moved, or manipulated by the lever. It can be in the form of a physical object or any force opposing the applied force.
4. Effort: Effort refers to the force applied to the lever to overcome the load or resistance. It can be in the form of pushing, pulling, or any other force applied to one end of the lever.
Now that we understand the basic components, let's explore some terms associated with levers:
5. Mechanical Advantage: Mechanical advantage is a measure of the lever's effectiveness in amplifying force. It compares the output force (load) to the input force (effort). A lever with a higher mechanical advantage requires less effort to move a heavier load.
To calculate mechanical advantage, you can use the formula:
Mechanical Advantage (MA) = Load (L)/Effort (E)
6. Class 1 Lever: A class 1 lever has the fulcrum positioned between the load and the effort. This means that the load and the effort are on opposite sides of the fulcrum. Examples of class 1 levers include seesaws and crowbars.
7. Class 2 Lever: In a class 2 lever, the load is positioned between the fulcrum and the effort. This arrangement allows the lever to multiply the force applied to lift the load. A classic example of a class 2 lever is a wheelbarrow.
8. Class 3 Lever: A class 3 lever has the effort positioned between the fulcrum and the load. This type of lever provides more speed or distance instead of force amplification. Examples of class 3 levers include shovels and fishing rods.
It's important to note that levers can be found in various applications, from simple tools to complex machinery. Understanding these terms can help you analyze and design lever systems, predict their behavior, and calculate their efficiency.
