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. +----------------------------------------------------------------+ | Attachment filename: impact.jpg | |Download attachment: http://www.unicyclist.com/attachment/300643| +----------------------------------------------------------------+ -- jim.furfaro - Rocket Scientist Earth - Moon - Mars: Challange Traditions, Continue the American Adventure ------------------------------------------------------------------------ jim.furfaro's Profile: http://www.unicyclist.com/profile/7261 View this thread: http://www.unicyclist.com/thread/39658 |

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. -- U-Turn - As long as my feet keep movin'... Weep in the dojo... laugh on the battlefield.

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. -- tholub - Kinetic Sculptor ------------------------------------------------------------------------ tholub's Profile: http://www.unicyclist.com/profile/804 View this thread: http://www.unicyclist.com/thread/39658 |

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? -- munipsycho - CrashTestDummies are us. ===================== The UniSkills Assessment: www.munipsycho.com/uniskills_2.jsp I can fly too.
