A
first-class lever is a type of lever where the
fulcrum (pivot point) is located between the effort (input force) and the load (output force).
The arrangement is: Effort = Fulcrum − Load
· A
pair of scissors consists of two levers joined at a fulcrum in the center.
· The
effort is applied at the handles.
· The
load (cutting force) is exerted on the blades.
· The
fulcrum is the pivot or hinge in between, making it a
first-class lever.
