Respuesta :
The fulcrum is located between the input and output forces. The output force is always in the opposite direction to the input force in a first-class lever.
Answer:
First class lever.
Explanation:
There are three classes of lever i.e.
1. First class lever : In this type of lever, the fulcrum is in between the input and output force
2. Second class lever : In this type of lever, the resistance force is in between the fulcrum and the effort.
3. Third class lever : In this type of lever, effort is placed between the fulcrum and the resistance force.
So, in first class lever, the fulcrum is in between the input force and the output force.
