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
