Cool keyboard player ?

What about the guy that wrestled his heavy Hammond B3, wedged knives in the keys,

somersaulted while playing a concert piano (WITH the piano and seat belt),

blew up his Moog Synthesizer, played Bach classics standing on the opposite side of the keys,

all this in 3-hour concerts that had everything from jazzy acoustic improvisations

to full-blown electric bombast prog rock and pure rock´n roll ?

RIP Keith Emerson.

Windy weather. If I think back to when I started driving, 105E Anglia, Mk1 & Mk2 Cortina, Mk 1 Escort, Mini, any really windy weather from cross winds and you got blown all over the place.

Modern cars not so much. Why?

Manufacturers are more savvy about aerodynamics, true, but would have thought that something designed to have least resistance in a straight line, which is 99.99% of the time, then wouldn't they be more affected by large crosswind gusts?

OK, cars are also a lot heavier, that would improve things, but they are also a lot larger so more area in side profile so that works the other way and increases susceptibility.

Good point, that was an issue with early Sierras. Something about the centre of pressure being a long way forward.

wider tyres, with better grip, will contribute a lot.

cross-ply tyres, live rear axles, wind-catching roof-rails.

The suspension in the S-Class (and I'm sure in other things too) detects cross-winds and compensates accordingly.

Here's a strange one.

There are loads of videos on YouTube of really tarty trashy looking women cranking Citroen 2CV's that are reluctant or rigged not to start.

I could understand the odd one, but there are loads, it's like a weird "to do" thing, hire a Russian prostitute and then film her cranking a 2CV.

Why?

Looks like a fetish thing based on the amount of clevage on show. The less time spent trying to understand another persons fetish the happier a life you'll lead!

Say I have a rope with a breaking strain of 50kg.

I need to cross a chasm by swinging on the rope, but I weigh 100kg.

If I throw the rope over a convenient branch hanging over the chasm, so it loops down and I can hold both ends, will it support 100kg (as it is now a double rope)?

A mate swears it will, and I say it won't - it will still only hold 50kg.

Who wins?

If you keep the tension equal on both ends, I think your mate is right.

If you just looped it over then I reckon it would break as you're still relying on essentially one piece of rope over the branch. However if you tied both ends to the branch then hung off the double rope you should be ok.

I think...

I think in that case it's effectively two 50 KG weights pulling in opposite directions at the branch end so I don't think it will hold.

If it's wrapped around the branch once or twice, friction counteracts the "opposite" tension.

A bit blowy yesterday, so wind turbines.

I expect they come in different specifications, but are they able to still be used in such windy conditions without having to turn the blades out of the wind? And, how do they cope with the gusts?

The Mrs has a new model Renault Twingo, and that is the worst car I've ever driven in crosswinds. It was so bad on one motorway journey that the sideways movement triggered the ESP! I've driven unladen LWB Transits with better stability
