To understand the different types of levers, you can refer to a reliable source of information like Wikipedia. Here's the direct link to the Wikipedia page on levers:

On this page, you will find detailed explanations, diagrams, and examples of the different types of levers: first class, second class, and third class levers.
To determine the type of lever, you need to consider the relative positions of three components: the fulcrum (the point where the lever pivots), the input force (the force applied to the lever), and the output force (the force exerted by the lever).
In a first class lever, the fulcrum is located between the input and the output forces. Examples of first class levers include a seesaw and a pair of scissors.
In a second class lever, the output force is located between the fulcrum and the input force. A classic example of a second class lever is a wheelbarrow, where the wheel acts as the fulcrum and the load is between the wheel and the handles.
In a third class lever, the input force is between the fulcrum and the output force. Examples of third class levers include a fishing rod or a baseball bat.
By examining the positioning of these three components, you can identify the type of lever being used. The Wikipedia page will provide you with further details and examples for better understanding.
