(b)
Figure 2.1 shows a wheels vehicle mode. The mass of the vehicle is 1920 kg
and the distance between centre of mass to the front and rear axles are 1.5 m
and 1.6 m respectively. If the rolling resistance coefficient between road and
tire is fo = 0.0165 when the vehicle travel at a speed of v = 30 km/h with
steering angle of å = 20°, front and rear slip angles at 3° radius of turning R is
7.603m; then :
i.
Calculate the cornering forces of the front and rear wheels.
ii.
Calculate the rolling resistance of the tire.
ii.
What happens if the speed is increased to 50 km/h?
