Mechanisms: Levers
Different classes
Class 1
The load and effort are on opposite sides of the fulcrum.
The effect of the effort applied can be multiplied or reduced depending on where the fulcrum is in relation to the load.
Class 2
The load is between the effort and the fulcrum.
The effect of the effort is always multiplied (d>r).
Class 3
The effort is between the fulcrum and the load.
The effect of the effort is always reduced (d<r).
They are classified according to the possition of the load and effort applied in relation to the fulcrum.
-
Law of the lever
It's when the lever is balanced when the effort (F), multiplied by its distance (d) is equal to the load (R) multiplied by its distance from the fulcrum.
-
What are they?
A rigid bar used with a point of support (fulcrum).
The mechanical force (effort) is applied on one end of the lever (F) with the aim of counteracting the resistance of the load (R).
