I thought I would add some more fuel to the fire on the helmet debate.
I have included a graph on impact survival experience from NASA-STD
3000. One point that you should note is that a head impact from a
standing position (no added riding velocity) is on the edge of
survivability. This assumes that the person's head is the first thing
to hit the ground and the ground did not absorb any of the impact
(concrete). Hope this helps with your debate.

*Why would one compare the size and mass of a helmet to that of the
human body? Last time I checked, most people wore helmets just on
their head.*
Because a poster above was talking about center of mass. The COM of a
person would be essentially unchanged by adding a helmet. As far as
size goes, the size of the body compared with the size of the helmet
means that the helmet is way less than 1% of the volumetric footprint of
the body. So as far as an accident goes, the size of a person is
unaffected by a helmet. Therefore, the class of accidents is unchanged
by the addition or deletion of a helmet.

*Which engineer are you talking about? Yourself? *
Yup.

*I would have a problem making such a statement. There are 1,001 ways
to smash a helmet, and 1,001 ways to smash your head, but the two
events are not 100% correlated.
*
Why do you think 100% correlation is required? If a helmet saves death
or injury in a reasonable subset of accidents (it does), then it is
worth wearing.

Let's be realistic; a helmet sticks out way further in back than your
head does, and it raises the rotational center of gravity while adding
weight. So the fact that you hit your helmet, especially on the back
point like that, is not at all proof that you would have hit your head
were you not wearing a helmet.

Let's face it. There are just too few candidates for the Darwin awards
lately.

So if anyone doesn't want to wear a helmet, I say fine. Let 'em wear a
ziplock baggy full of pudding if they want. Or not.

In either case, it will be all in good clean fun when we pass the
entertaining story of their death around via email next year.

Thanks in advance for the laugh.

BTW, can I have some of your stuff? Your Uni? Or maybe the unused
helmet? Any unopened pudding at least?

What I want to know is why he only noticed the helmet damage -five- days
after the crash...
