A block and tackle system of pulleys has a velocity ratio 4.
What is the value of the mechanical advantage of the given pulley system if it is an ideal pulley system?

Explanation

To find the mechanical advantage (MA) of an ideal block and tackle pulley system given that the velocity ratio (VR) is 4, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Velocity Ratio (VR)**: This is the ratio of the distance moved by the effort to the distance moved by the load.
- **Mechanical Advantage (MA)**: This is the ratio of the load lifted to the effort applied.
