there is no such thing as a 4th class lever
A fourth-class lever is a type of lever where the input force is between the fulcrum and the output force. In this arrangement, the load arm is longer than the effort arm, resulting in an increase in speed but a decrease in force. Fourth-class levers are not very common in everyday situations but can be found in certain biological systems, such as in the human body.

The Class Lever for Pliers is a class 2 lever.
Class 3 Lever! You Don't even know that!
A carjack is a class 2 lever because the load (the car being lifted) is between the effort (the force applied to the handle) and the fulcrum (the contact point with the ground).
A class 1 lever is typically used in a beam balance. In this type of lever, the fulcrum is located between the effort (applied force) and the load (object being weighed). This arrangement allows for precise and accurate measurement of weight.
class 3
A domino can be considered a class 1 lever where the pivot (fulcrum) is at one end, the force (push) is applied at the other end, and the load (domino) is in between. This is similar to a seesaw.
no. a catapult is a class-3-lever not a class-1-lever.
It is a third class lever.
A crane is a first class lever when it is winching in or out the rope attached to a load. The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
