Under conditions of braking or acceleration of a road vehicle, a load
transfer between front and rear wheels occurs. The problem of load
transfer arises since the accelerating or braking force is not applied to
the centre of gravity of the vehicle but to the point of contact of the
wheels with the road.
The Braking and Accelerating Forces Apparatus has been designed to
demonstrate this load transfer and to enable the student to carry out
simple experiments to investigate the relationship between the forces
involved in vehicle braking and acceleration. The relationship between
these forces on front wheel drive, rear wheel drive, and four wheel drive
may also be demonstrated.
