Question

You use a lever with a mechanical advantage of 30. How heavy a load can you lift with an effort of 100 N?

Answer 1

Step 1: Given data:

Mechanical advantage = 30

Effort = 100 N

Step 2: Finding the load

$\raisebox{1ex}{$Mechanicaladvantage=load$}\!\left/ \!\raisebox{-1ex}{$effort$}\right.$

After putting values we get,

$30=\raisebox{1ex}{$load$}\!\left/ \!\raisebox{-1ex}{$100$}\right.$

$load=100\times 30N$

$load=3000N$

Hence, the load can you lift with an effort of 100 N is 3000 N.
