A block and tackle pulley system has a velocity ratio 3.
Draw a labelled diagram of this system. In your diagram, indicate clearly the points of application and the directions of the load and effort.

Explanation

### Step-by-Step Solution:

1. **Understanding the Block and Tackle Pulley System**:
A block and tackle pulley system consists of multiple pulleys (blocks) that work together to lift a load with less effort. The velocity ratio (VR) indicates how many times the effort distance is greater than the load distance. In this case, the VR is 3.

2. **Drawing the Fixed Support**:
Start by drawing a horizontal line to represent the fixed support at the top of your diagram. This is where the pulleys will be attached.
