Technician A says that as wheelbase becomes shorter in a highway truck,its resistance to yaw is reduced.Technician B says that an ABS add-on called directional stability control uses the brake system to avoid tracking yaw.Who is correct?

A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Yaw

Vehicle lateral tracking off the intended straight-ahead or turning radius; a vehicle traveling sideways in a skid would be an extreme case of yaw.

Wheelbase

Dimension of a tandem drive axle truck measured between the center of the front axle and the centerline of the tandem bogie. In a two-axle vehicle, it is the distance between the centerline of the front and rear axles.

Directional Stability Control

A vehicle safety system that helps maintain the vehicle's intended direction of travel, typically under adverse conditions.

  • Understand the implications of vehicle dynamics, such as wheelbase and yaw resistance, on braking and stability control systems.

Final Answer :
C
Explanation :
Technician A is correct because a shorter wheelbase does indeed reduce a vehicle's resistance to yaw, making it more susceptible to turning or spinning out. Technician B is correct because directional stability control, an add-on to ABS, uses the braking system to help maintain the vehicle's intended path and avoid yaw or skidding, enhancing stability.
