Answer:

MA = 0.5

Explanation:

The mechanical advantage is defined as:

MA = Resistance_force / Effort_force

Resistance_force = 9 N

Effort_force = 18 N

We substitute,

MA = 9N / 18 N

MA = 0.5

Answer:

MA = 0.5

Explanation:

MA = (Useful Force) / (Input Force)

MA = (18 - 9) N / 18 N = 9 / 18

Hence, MA = 0.5

Answer: MA = 0.5
