If we compare the effort arm length with the load arm length in a class 3 lever, then which of the below is true?

A.

effort arm length can be greater than, equal to or less than the length of the load arm

B.

effort arm length is always = load arm length

C.

effort arm length is always < load arm length

D.

effort arm length is always > load arm length

Correct option is C


A class 3 lever is characterized by the following:
· The effort is applied between the fulcrum and the load.
· Examples include a fishing rod, tweezers, or a broom.
· The effort arm (distance from the fulcrum to the point where effort is applied) is always shorter than the load arm (distance from the fulcrum to the load).
