Question

Calculate the mechanical advantage of a lever when effort = 5 kg wt and load = 45 kg wt

Answer 1

Step 1, Given data

Effort = 5 kg = 50 N

Load = 45 kg = 450 N

Step 2, Finding the mechanical advantage

We know,

The mechanical advantage of a lever is given as

$MA=\frac{Load}{Effort}$

Putting all the values and solving

We get,

$MA=\frac{450N}{50N}=9$

Hence the mechanical advantage of the lever is 9.
