Question

What are the uses of 1st class leaver?

Answer 1

Answer:

First class levers always change the direction of the input force, unlike second and third class levers. The fulcrum is always in between the input force and the out put force. First class levers can multiply the force or the distance depending on where the fulcrum is placed and where the forces are applied. A first class lever can be something as simple as a crow bar or a pair of scissors.
