Answer 2

Mass of car m=1800kg

Distance between front and back axles d=1.8m

Distance between center of gravity and front axle=1.05m

Let R

b

and R

f

be the forces exerted by the level ground on the back and front wheels respectively

At translational equilibrium:

R

f

+R

b

=mg=17640 N

(i)

For rotational equilibrium, on taking the torque about the C.G., we have:

R

f

(1.05)=R

b

(1.8−1.05)

⟹R

b

=1.4R

f

(ii)

Solving (i) and (ii) gives

R

f

=7350 N

R

b

=10290 N

The on each front wheel =7350/2=3675 N

The on each back wheel =10290/2=5145N
