The pulley system drawn lifts a load of 150 N when an effort of 60 N is applied. Find its mechanical advantage.

Explanation

To find the mechanical advantage (MA) of the pulley system, we can follow these steps:

### Step 1: Identify the given values
- Load (L) = 150 N
- Effort (E) = 60 N

### Step 2: Write the formula for mechanical advantage
The formula for mechanical advantage is given by:
