Answer:C: multiply the input force
Explanation:
A lever is a simple machine consisting of a bar pivoted or supported at a point (known as Fulcrum) about which it can rotate to perform the task.
Mechanical Advantage MA = [tex]\frac{E}{L}=\frac{F_{L}}{F_{E}}[/tex]
where E→ length of effort arm from the pivot
L→ length of load arm from the pivot
[tex]F_{E}[/tex]→ force on the end of effort arm
[tex]F_{L}[/tex]→ force on the end of load arm
By the law of conservation of angular momentum:-
[tex]F_{E}\times E[/tex]=[tex]F_{L}\times L[/tex]
