The car shown in Fig. 5 complete with driver has a mass of 815 kg and without the two aerofoils has a 50% - 50% front - rear weight distribution at a certain speed at which there is no lift on the car. It is estimated that at this speed each of the aerofoils A, and A, will generate 2 kN of downforce L and 250 N of drag force D on the car. Determine the vertical reactions under the two pairs of wheels at that speed when the aerofoils are added. Assume that the addition of the aerofoils does not affect the drag and zero-lift conditions of the car body itself and that the engine has sufficient power for equilibrium at that speed.

The car shown in Fig. 5 complete with driver has a mass of 815 kg and without
the two aerofoils has a 50% - 50% front - rear weight distribution at a certain speed at
which there is no lift on the car. It is estimated that at this speed each of the aerofoils
A, and A, will generate 2 kN of downforce L and 250 N of drag force D on the car.
Determine the vertical reactions under the two pairs of wheels at that speed when the
aerofoils are added. Assume that the addition of the aerofoils does not affect the drag
and zero-lift conditions of the car body itself and that the engine has sufficient power
for equilibrium at that speed. The weight of the aerofoils may be neglected.
