<span>The answer is: 2. 11 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>
