During rapid acceleration, which load transfer occurs?

During rapid acceleration, which load transfer occurs?

• A. Lateral transfer
• B. Longitudinal transfer
• C. Weight shift
• D. Centrifugal force

Answer: (B)

During rapid forward acceleration, the vehicle’s inertia resists the change in motion, creating an inertial load that acts through the center of gravity toward the rear. This causes the weight to transfer along the length of the vehicle from the front axle to the rear axle, lightening the front wheels and loading the rear wheels more. This specific effect is called longitudinal load transfer. It’s different from lateral transfer, which happens in turns as weight shifts side to side, and from centrifugal force, which is a commonly invoked idea but not the primary mechanism here. Weight shift is the general idea, but the precise term for what occurs during acceleration is longitudinal load transfer.
