Write down the relation between the load and the effort of the pulley system.

Explanation

To derive the relation between the load and the effort in a pulley system, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Components**:
- In a pulley system, we have a load (mass) denoted as \( mg \) (where \( m \) is the mass and \( g \) is the acceleration due to gravity).
- The effort is the force applied to lift the load, denoted as \( T \) (tension in the rope).
