In class 1 levers, effort and load moves in ______.

Concept:

Levers:

• Levers are the most basic machines which are used to do some work with minimal effort.
• A lever amplifies an input force to provide a greater output force, which is said to provide leverage.
• Types: First class lever, second class lever, third class lever.

Class 1 levers:

• It is a very simple machine comprised of a beam placed upon a fulcrum.
• A load is placed onto one end of a beam, while an effort is directed onto the other end to counter the load.

• In a first-class lever, the effort (force) moves over a large distance to move the load a smaller distance, and the fulcrum is between the effort (force) and the load.
• Examples of first-class levers are pliers, scissors, a crowbar, a claw hammer, a see-saw, and a weighing balance.

Explanation:

• A 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.
• The effort in a class 1 lever is in one direction, and the load moves in the opposite direction.​

Additional Information

Second class lever:

• In this class of lever, the load is applied in between the fulcrum and the effort force.
• Examples: Wheelbarrow, Nutcracker, etc.

Third class lever:

• In this class of lever, the fulcrum is at the one end and the effort force is applied in between the fulcrum and load.
• Examples: Human arms, Tongs, tweezers, etc.
• It consists of two levers which works together.
