INTERESTING FACT OF THE DAY

[Bibio]

did you know that the hero blobs on the end of motorcycle foot pegs are set for a lean angle of 45 degree on that bike. why? as that's the safest lean angle for almost every single road tyre and its not until you get to racing tyres that the angle goes to 50 degree.

so remember peeps if your grinding your pegs then its a safe bet your running out of rubber.

About 99% of our DNA sequence is the same as other humans. And 70% is shared with slugs.

Before waxed thread was commonly available seamstresses would use their own earwax to stop the cut ends of threads from fraying.

In the 1400's a law was set forth in
England that a man was allowed to beat
his wife with a stick no thicker than his
thumb. Hence we have 'the rule of
thumb'

I do believe that is not correct. There has never been any such law, (aside from the fact there was no statute as such in the 1400's for a law to be set forth in).

I have heard two competeing origins for "The Rule of Thumb". First is that carpenters would use their thumbs as a measuring devise, which was convienient and reliable, if not always accurate.

The other (and my favourite) is that brewers used their thumbs to test the temperature of beer as it was brewing. I think this is because it was supposed to brew at 60 degrees (i think) which is about as warm a liquid as you can put your thumb in.

The Lockheed SR-71 (the Blackbird spyplane), had engines where ~80% of the thrust was provided by the shockwave of its forward motion. This effect was so pronounced, that when the Russians fired missiles at them and the crew evaded the missiles by accelerating and out running the missiles, the crew would report that they were ahead of their fuel curve. The plane was actually more efficient by both fuel per minute and fuel per mile at higher speeds.

The fusilage would heat up inflight and expand by as much as a foot, to cope with this the panels would be loose and ill fitting whilst on the ground and the plane would leak fuel and hydraulic fluids. Becuase of this the SR-71 would have to take off with a nearly empty tank, then perform a series of climb and dive manouvers to heat the plane up, before fuelling in flight and carry out the rest of the mission.

And my favourite fact about the Blackbird (I have many many more). Engineers at Lockheed initially had a large budget to develop sleeping arrangements for the two man crew (missions could last up to 48 hours). A lot of this was spent untill an intern showed up one day with two $10 reclining lawn chairs, which could be stowed easily in the cabin when not in use, and massively exceeded all other specifications in the design brief.
