Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
