Answer 2

Heyy mate... Good evening!!!

Answer:

Class 1 lever has the fulcrum placed between the effort and load. The movement of the load is in the opposite direction of the movement of the effort. This is the most common lever configuration.

Note that the length of the effort arm can be greater than, equal to or less than the length of the load arm in a class 1 lever.

Examples of class 1 levers include:

Teeter-totter

Oars on a boat

Catapult

Shoehorn

Scissors

Pair of pliers

Class 2 lever

A Class 2 lever has the load between the effort and the fulcrum. In this type of lever, the movement of the load is in the same direction as that of the effort. Note that the length of the effort arm goes all the way to the fulcrum and is always greater than the length of the load arm in a class 2 lever.

Examples of Class 2 levers include:

Wheelbarrow

Crowbar

Nut cracker

Wheelbarrow i

Class 3 lever

A Class 3 lever has the effort between the load and the fulcrum. Both the effort and load are in the same direction. Note that the length of the load arm goes all the way to the fulcrum and is always greater than the length of the effort arm in a Class 3 lever. Also, load in a Class 3 lever moves in the same direction as the effort.

Examples of Class 3 levers include:

Tweezers

Stapler

Mousetrap

Broom

Hockey stick
