Answer:
4
Explanation:
Mechanical advantage is defined as the ratio of the load to the effort applied to raise the load. If minimal effort is used to overcome a much larger load, that is when we have what is called mechanical advantage i.e a machine has been used to our advantage.
Mathematically, MA = Load/Effort
Given parameters
Load = 160N
Effort = 40N
Required
Mechanical Advantage
Using the formula above
MA = 160N/40N
MA = 4
advantage
