A simple machine is used to lift a load of $150\text{ N}$ by applying an effort force of $30\text{ N}$. What is the mechanical advantage (MA) of this machine?
  1. $0.2$
  2. $5$
  3. $120$
  4. $4500$

Solution

Mechanical Advantage is calculated as Load divided by Effort: $\text{MA} = 150\text{ N} / 30\text{ N} = 5$.
