a person uses a movable pulley system to lift a 120 N load. the effort force applied is 60 N. what is the mechanical advantage of the pulley system?

Answer 1

The mechanical advantage (MA) of a pulley system can be calculated using the formula:

\[ \text{Mechanical Advantage} = \frac{\text{Load}}{\text{Effort}} \]

In this case:

• Load = 120 N
• Effort = 60 N

Now, substituting the values into the formula:

\[ \text{Mechanical Advantage} = \frac{120 , \text{N}}{60 , \text{N}} = 2 \]

Thus, the mechanical advantage of the pulley system is 2.
