The following figure shows the use of a lever.
(i) Give an example of this class of lever and
(ii) if FA= 10 cm, AB= 510 cm, calculate the minimum effort required to lift the load.

This is a class III-leyer. The tong is a class III lever, In the figure,
`"Effort "xx" effort arm" = "load "xx "load arm"`
i.e., `E xx AF= L xx FB`
`implies EN xx 10 cm=50 N xx 500 cm`
`implies E= (50N xx 500 cm)/(10 cm) =2550 N`
