I asked a question recently about how
quick this pressured vessel will vent.
I have attached a sketch :-
Can someone show via some formula how
long it will take to vent, or at lest
drop half its pressure ?
Thanks a lot !
I would like to know what the coefficient of friction u,
and the nut factor k, is for a nut tightening on a bolt,
for stainless steel, on stainless steel. I have not been
able to find this value.
For mild steel on mild steel, Gr 8.8 bolts :-
u =0.15, and k = 0.2
If someone can clarify this...
I am a Structural Engineer, working in the offshore oil and gas industry.
I am looking for a computer program that can design 4 leg slings,
in accordance with the commonly used codes, in this industry.
Can anyone tell me if there is such a computer program ?
Thanks, Bert.
Can someone plese tell me whether an angle, i.e. a L shape has a plastic neutral axis. Because I have just used a program which gave ( second moment of areas ) Zpl,x & Zpl,y, as both equal to 0 ?
For AISC, which method, LRFD, or ASD, should one use ?
I am a Structural Engineer in the oil and gas industry, in Aberdeen, Scotland, U.K.
In this industry we use some of the American codes, e.g. the AISC codes.
ASD is the allowable stress design. I have the 'green book', 9th edition, dated...
I have found a web site that has a great spreadsheet, for working out the section properties of a plate girder ( I, or T shapes ).
The programe is top quality and very well presented.
I frequently add the design sheet into my calcs.
The web site is :-
( on the menu on the left side, go to...
I am desperately looking for a combined bending and compression, column design spreadsheet, in accordance with the AISC codes.
Previously someone referred me to the MITCalc website, however the spreadsheet on there is not very useful for a Structural Engineer.
There must be people whom have...
In Europe, 4 leg lifting slings are designed, and certified in accordance with BS EN 13414.
In the USA, when a sling manufacturer produces a sling, does he stamp on the sling, that it is certified, in accordance with a particular code ?, if so what code is it ?
Can anyone tell me where I can get a combined bending and compression steel column design spreadsheet, to AISC rules from ?
If anyone has produced one, could you please give me a copy. Perhaps I have something that I could swop for it ?
The old imperial system of units which we British discarded in favour of the SI ( metric ) system of units, was a total joke. In hindsight I can believe that we British invented such a stupid system, it could only have happened in Britain !. If someone was simple, and completely drunk, they...
Hi, I am a British Engineer.
I was wondering if any of you could tell me what the American code is for the design, and manufacture of a 4 leg lifting sling ?
i.e. the ropes e.t.c. that a crane requires to lift a heavy object.
