need someone with brains to answer a Q :)

[berley]

What is meant by the following: t ≥ 200 ? m?

Don't ask me what its in relation to as I don't know myself but at a guess, it something to do with microns ?, hubby asked me to google it for him but I cant find the answer If it's any help he's a Paint Inspector so it might have something to do with paint as well

[benny/9]

is this any help

hmm by what i can gather 200 ? m is 2/10s of a millimeter so its a measurement as for t ≥ they are mathematical symbols

@ benny nope the google link was no help, I'd already read a few of the links and was none the wiser

@ GMB you've got further than me with this part of it "by what i can gather 200 ? m is 2/10s of a millimeter " keep trying pleeeeeeese

@GMB I notice you've edited your post to say that - t ≥ is a mathematical symbol, I kind of gathered that it was an algorithm/maths symbol, but he cant answer the Q with

maths symbol for 2/10s of a millimeter, can he

I have been scraching my head for an hour, Meat will have your answer

[gmb45]

≥ means greater than

[berley]

@ SJ thanks for trying, at GMB you just need to find out what the "t" means now and give me the complete answer please

so have we got as far as the answer being

(something) greater than 2/10s of a millimeter ?

[gmb45]

hmm in math t means time

[berley]

your getting there GMB, can anyone else give a complete answer ?

Thickness is greater than or equal to 2/10ths of a millimetre. 100 ?m – 1/10 of a millimetre

[berley]

Thickness is greater than or equal to 2/10ths of a millimetre. 100 ?m – 1/10 of a millimetre

Is that the right answer or are you taking the piss that none of us knew it ? and if that is the right answer then my hubby is gonna get it in the neck as he should have known that without asking me to google it

[DOUGALMCD]

100 um is the thickness of a coat of paint.

I don't have the answer berley but I do know that in specialised painting, such as the underside of a boat or ship, paint has to be applied in specific thickness which I think is measured in 'microns'.

T is the shear test

From fluid mechanics, for a Newtonian fluid, the shear stress, τ, on a unit area moving parallel to itself, is found to be proportional to the rate of change of velocity with distance perpendicular to the unit area:

kind of simple isn't it
Meat knows this its just he's playing hard to get

maybe he is trying to tell ya you need a new perm
