April 8, 1933: For those who have visited London and wondered how they know their double-decker buses won’t fall over, this is apparently how they find out. Per police regulation, employees of the London General Omnibus Company put their 60-person bus to a “tilt test,” putting it on a 28-degree angle. Photo: The New York Times
False sense of security since empty is not the same as loaded, let alone the variable associated with differing passenger weights....
ReplyDeletetext says 28, gauge says 35
DeleteThe platform was at 28, the bus at 35 (probably due to its suspension)
DeleteAlso, "static" versus "dynamic"

ReplyDelete400 gallons of nitro?
DeleteWhile it's useful information from a static point of view, of course it would never happen that a bus tips because it's traversing an incline. It happens under speed, because of angular acceleration, usually swerving to avoid something. I guess the measurement could be applied to a calculation of overturning moment.
ReplyDeleteThey should run that test on riding lawnmowers.
ReplyDeleteChiswick bus depot. They made the Routmasters specifically for London roads. Large skid pan drivers had to learn on also.
ReplyDeleteThe body work looks like its leaning off the chassis?
ReplyDeleteThe chassis is chained to the platform.
