1. What is Front End Load?

Front End Load refers to the weight distribution on the front axle of a truck. It's calculated based on the total weight of the vehicle, the distance from the front axle to the center of gravity (CG), and the wheelbase length.

2. How Does the Calculator Work?

The calculator uses the Front End Load equation:

\[ Load = Total\ Weight \times \left(\frac{CG\ Distance}{Wheelbase}\right) \]

Where:

\( Total\ Weight \) — Combined weight of the truck and its load (lbs)
\( CG\ Distance \) — Distance from front axle to center of gravity (feet)
\( Wheelbase \) — Distance between front and rear axles (feet)

Explanation: The equation calculates the proportion of total weight that's distributed to the front axle based on the position of the center of gravity relative to the wheelbase.

3. Importance of Front End Load Calculation

Details: Proper front end load calculation is crucial for vehicle stability, braking performance, tire wear, and overall safety. Overloading the front axle can lead to steering difficulties and increased stopping distances.

4. Using the Calculator

Tips: Enter total weight in pounds, CG distance in feet (from front axle to center of gravity), and wheelbase in feet (distance between axles). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical front end load percentage?
A: For most trucks, 25-35% of total weight on the front axle is typical, but this varies by vehicle design and load distribution.

Q2: How does front end load affect handling?
A: Excessive front end load can make steering heavier and reduce rear wheel traction, while too little can make steering overly light and reduce braking effectiveness.

Q3: When should I be concerned about front end load?
A: If your calculated front end load exceeds the manufacturer's Gross Axle Weight Rating (GAWR) for the front axle, or if it's less than 20% of total weight.

Q4: How can I adjust front end load?
A: By repositioning the load (moving it forward or backward), adding or removing weight, or adjusting the fifth wheel position on tractor-trailers.

Q5: Does this calculation apply to all vehicles?
A: This basic calculation works for most two-axle vehicles. More complex formulas are needed for vehicles with multiple axles or articulated vehicles.
