Question

What do you mean by first class lever? Explain with examples.

Answer 1

It is a type of lever which has the fulcrum in between the weight and the force applied. Its order is represented as force-fulcrum-weight. This is the most basic type of lever.

Example:

• Our hand pushing an object or seesaws, crowbars.
• Using scissors represents the use of two first-class levers.
• A wheel and axle is also an example.
• Pulling a nail out of a wooden plank also represents a first-class lever.
