Practice question

What dynamic axle load transfer occurs when a bus undergoes heavy braking from 80 km/h to a stop?

  1. Mass shifts towards the rear axle, significantly reducing front tire contact pressure
  2. Dynamic load shifts forward to the front steering axle, compressing front suspension and unweighting the rear drive axle
  3. Axle loads remain statically identical regardless of braking force
  4. Load shifts entirely to the curbside tires due to road camber

Answer: B — Dynamic load shifts forward to the front steering axle, compressing front suspension and unweighting the rear drive axle
