As we explained in earlier chapters, the
air resistance to the motion of a vehicle
is something important that engineers
investigate. The drag force acting on a
car is determined experimentally by
placing the car in a wind tunnel. The air
speed inside the tunnel is changed, and
the drag force acting on the car is
measured. For a given car, the experimental
data generally is represented by a
single coefficient that is called drag
coefficient. It is defined by the following
relationship:
F,
where
air resistance for a car that has a listed
C, = drag coefficient (unitless)
measured drag force (N)
drag coefficient of 0.4 and width of 190 cm
and height of 145 cm. Vary the air speed
in the range of 15 m/s
