**Figure 10.8**: Performance chart for a 22-ton rear-dump truck

### Explanation of the Diagram:

The chart is divided into two main sections, displaying performance metrics for a 22-ton rear-dump truck.

#### Top Graph:
- **X-Axis (Top)**: Represents the total resistance as a percent of vehicle weight, ranging from 0 to 40.
- **Y-Axis (Left)**: Displays vehicle weight in thousands of pounds, ranging from 0 to 300.
- **Lines and Labels**:
  - Various diagonal lines represent different conditions or performance metrics. Two key labeled lines are:
    - **Rated GVW** (Gross Vehicle Weight)
    - **Rated NVW** (Net Vehicle Weight)

#### Bottom Graph:
- **Y-Axis (Left)**: Shows speed in miles per hour (mph), ranging from 0 to 50.
- **X-Axis (Bottom)**: Represents rimpull in thousands of pounds, ranging from 0 to 150.
- **Gear Indicators**: Curved lines labeled as Fifth, Fourth, Third, Second, and First, indicating the performance characteristics in different gears.

### Performance Chart Details:

- **Engine**: GM 6-71N at 238 hp
- **Transmission**: Fuller 5GT-1220
- **Axle Ratio**: 16.00/1
- **Tire Size**: 16.00-25
- **RoRa**: 28.6 inches

This detailed information helps in understanding the vehicle performance by illustrating the relationship between speed, rimpull, vehicle weight, and total resistance at various operating conditions.
