Driver-Once-More:
Huge wind turbine blades en route to Fraisthorpe - BBC News
Stand in front of it and blow, really hard? It works with the little windmills in my garden!
Seen these been moved in France on small D roads.
A lot of accuracy needed, roundabouts might need sign to be dismantaled and reinstalled.
Lot of foot work by the ■■■■■■ people too to make sure it all runs smoothly
With so many of these windmills going up in the UK, I would think its now quite a routine job for the people that do it.
Each 197 foot long ■■? is that not the diameter of the ‘fan’ when assembled ?
As obviously a lot of planning has to come into these abnormal loads, does the driver get a chance to rehearse the route, or does he just roll up relying on his previous experience and knowledge? 
Or does that only come into play when obstructions, are having to knowingly be removed in advance…

the bigguns now are 120m diameter. so yes 200’ for each blade.
A little while ago I was watching one of these monsters gracefully turning, 12rpm. I was curious how fast the tip was going, I was thinking 30 or 40 mph … how wrong could I be, at 12rpm the tip is doing a 170mph, so marginally faster than the tip of a 9" grinder.
When I was in the RAF in heavy haulage we had a dedicated crew that would drive the route before by car and measure everything to make sure we could get through, a lot of planning would go into it before we moved anything and as far as I can remember we never had any problems en route and dont remember too much having to be moved or dismantled. Which surprised me when I heard the other day the two wide loads had become stuck at I think Cathorpe, i would have somebody would have checked before they went ( i only heard this from the news so my info maybe not quite right but thats what I heard)

You do realise that OTHERS are now on google, and will be along shorty to dispute your statements! 
And before long we will have wheeled off into dynamics, masses and relative forces…
Until everyone wants to kill themselves!!!
Sorry, politics, religion and history modules are mandatory! 
Bugger just burnt me fingers on the grinder trying to measure the speed hehe

Cheers for that!
I just think that if I was ever to transport an abnormal load, I’m sure as hell i’d like to recon the route… 
I followed a wide load a couple of weeks through the centre of Reading (Oxford Rd), that had an ■■■■■■ car behind, but not in front from what I could see. He got really stuck in a few places and taking lots of tiny shunts to get around things (how I don’t know…) but they obviously hadn’t planned for the wire fencing on the outskirts of a building site. They were trying to hold it back to help the load get around with the excavator bucket! They still failed, as he still took some of the mesh, stripping it it of the frame! 
So i’m guessing they didn’t do a recon!
And possibly wished they had!
Or is it just another ordinary day in the haulage industry!

There is actually a maximum size these blades can be, otherwise the tips would break the sound barrier.
Angular speed is IIRC distance travelled divided by time taken, but is measured in radians per second (w or omega)
Bugger me, science teacher comes through!!!
Don’t go there!!!
(I beg you…)

They did some test runs prior to moving the real thing to find where the problems were.
Those useless monstrosities are to blame for the death of a countless number of lickle dicky birds 
And why did they not move them by ship to Brid and have a Chinook to place them direct on the site? A few more big smelly polluting lorries of the road as well !

I blame the socialists. Or Thatcher.

Our resident font of all will be along shortly to put us all right, don’t panic

there’s also more people die of radiation poisoning in the wind turbine industry than in the nuclear power industry,
I cant understand why we are hoping that wind power will keep the lights on.Surely marine energy is the way to go.The tides are predictable with huge amounts and weight of water moving in both the horizontal and vertical plane.

Back to school for you my lad…you have failed to take into consideration the effects of the coefficent of friction
