1) If you run your hand over the paintwork of the Ferrari F1 car does it
feel like sharkskin?

2) Which has more dimples?
a) The 2008 Mclaren F1 car
b) A Callaway HX golfball
c) DC's chin

3) A current F1 car sets off from rest in a 0-200 mph drag race. At what
speed (mph range) during this period is it accelerating fastest and why?
Why is this different to the behaviour of a normal road car?

4) A current F1 car does an emergency stop from 200-0 mph. How does the
rate at which it is scrubbing off speed (mph per second) vary during this
time and why?

5) How does 4 compare with the rate at which your own road car scrubs off
speed?

6) How much of a current F1 car's total suspension travel is in
a) the actual suspension?
b) the tyre sidewall?

7) A theoretical F1 car weighs 605kg, has 1cm static ground clearance and
develops a further 1200kg of downforce at 200 mph. Use this information to
calculate the minimum suspension spring rates it must use to prevent the
chassis bottoming out at top speed.

8) Is it possible for an F1 car to enter a corner such that at a certain
speed it loses adhesion and slides off the track but if the driver had
gone faster it would actually have made it round the corner? If so why?

9) An average family saloon has five gears, does about 120 mph and 1st gear
is good for about 35 mph or 30% of that. The next 4 gears fill the remaining
70% of the speed range. A current F1 car has seven gears so 1st should
occupy a smaller percentage of the total speed range than a family saloon's
1st gear. How much of an F1 car's speed range does 1st gear actually take up
and why?

10) Under what conditions is an F1 driver experiencing the most g force?
Acceleration, braking or cornering? How does this vary with car speed? How
do the figures compare with what you experience in your road car?
