A sudden jolt forward can do a lot of damage to a human. A long slow push can transfer way more energy with no damage. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236673 Thu, 17 Nov 2016 13:43:56 +0000 Rosie 236673@http://citycyclingedinburgh.info/bbpress/ <p>The Torygraph has been infected by the Daily Mail. It used to be responsible-conservative, now it's gone shrieky. Still employs Andrew Gilligan though (I think). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236663 Thu, 17 Nov 2016 12:49:07 +0000 I were right about that saddle 236663@http://citycyclingedinburgh.info/bbpress/ <p>@Frenchy</p> <p>Fifty shotgun blasts per second. Bang bang bang bang bang.</p> <p>The comparison is rhetorical, but you are correct. Shotguns are designed to damage things, cars not. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236659 Thu, 17 Nov 2016 12:29:28 +0000 Frenchy 236659@http://citycyclingedinburgh.info/bbpress/ <p>Is there a reason you're comparing the shot's <em>kinetic energy</em> to the car's <em>power</em>?</p> <p>A Mini Cooper weighs over 1000 kg. Travelling at even just 20 mph, that's a kinetic energy of 40 kJ. Of course, the shotgun can be more damaging because that 1.3 kJ is transferred to a much smaller region. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236656 Thu, 17 Nov 2016 12:17:36 +0000 I were right about that saddle 236656@http://citycyclingedinburgh.info/bbpress/ <p><em>Perhaps someone versed in the ratio of energy delivered in a collision to the cost of the corresponding repair work could comment.</em></p> <p>The lead emerging from a shotgun carries about 1.3kJ of kinetic energy. A small motor car can produce 75kJ per second. That's fifty shotgun blasts with the pedal to the metal. Body armour anyone? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236652 Thu, 17 Nov 2016 11:59:09 +0000 steveo 236652@http://citycyclingedinburgh.info/bbpress/ <p>I can't find it now but the Torygraph ran an article based on it and pretty much ignored all the points and just went with the petitioners points. Hardly surprising really. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17156#post-236603 Wed, 16 Nov 2016 20:40:49 +0000 gembo 236603@http://citycyclingedinburgh.info/bbpress/ <p>Was this not always a spoof?
