Question

Calculate the mechanical advantage of a lever when load = $200N$ and effort = $80N$.

Answer 1

Step 1, Given data

Load = $200N$

Effort = $80N$

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,

$MA=\frac{200N}{80N}=2.5$

Hence the mechanical advantage of the lever is 2.5.
