Erm... the walls don't quite meet

[Penners]

Frank - you have a point, but are you sure that it isn't just sprockets causing that curvature?

 

[kaz]

Just a quick up-date. The chappie that did the survey is coming back to take a look at the crack. I have really appreciated your interest and support... I'll give some feedback once I know more.

 

[Nemesis]

Well, we hope we don't have to lend you the scaffolding as we are using it, but an Acrow prop or two might be OK...

 

[Penners]

I'll give some feedback once I know more.

Please do.

Penners, an exponential curve is the shape, erm, a bit of old knicker elastic makes when its strung between two nails . Its a plot of Y =X^2 :roll:

[Penners]

Sorry, Frank, I don't agree. An exponential curve is one that increasingly increases (ie: logarithmically). A piece of elastic stretched between two nails is virtually a straight line - provided you're using top quality knicker elastic (like Nora Batty).

But I agree with your formula (as Nora would).

 

[Flyfisher]

Erm, I think that should be a catenary curve, assuming the old knicker elastic has really lost all its stretch.

OK, I'll get me anorak!

Back to maths school for you. Y=X^2 is a parabolic curve (which is the knicker elastic curve). An exponential curve is Y=e^X where e = 2.7182818 (approx). Petrol going up at 10% per month is an example of an exponential curve.

Gawd!, how embarassing , long time since I did any proper maths, sorry, Its my age you know.

Actually Flyfisher is correct. Non stretchy knicker elastic would be a catenary curve - though this is very close to a parabolic it isn't the same.

 

[Nemesis]

Non-stretchy knicker elastic would be a disaster, more like.

 

[shelli]

typical boys - every conversation becomes about knickers or similar

 

[Penners]

Well, I reckon it's all a load of parabolics anyway.

 

[Nemesis]

No, that's here:

although I say knickers to the nasty Little Chef infill, seems we stopped the planned demolition!

 

[shelli]

Well, Thank goodness they didn't demolish it - there simply aren't enough buildings that look like Wimples :roll:

Sam Scorer - very innovative roof structure, but was much better when a humble filling station.

No, it was never 'better'. It's silly and unattractive and showey-offey. I used to drive past it regularly on the A1, and I always thought it just looked like an annoyed nun.

What's more, it didn't keep the wet off you when you stopped for petrol, because at Markham Moor the rain falls sideways.

 

[chuckey]

Looks as though the management sat on Sams design for this one.

[Nemesis]

I always loved it. Made a big fuss about the proposed demolition. Glad it wasn't.

One day, hopefully, the ghastly Little Chef insert can be removed.
