Nogging is the English word for small pieces of timber (wood)inserted horizontally between studs. In Scotland they are called Dwangs and from your replies I believe you call them blocking in the USA. In Australia we also have short timbers called blocking used in other parts of timber framing...
Timber studs in Australia (& many countries ofthe world) are required to have nogging (dwangs) between studs at about 4'6" (1.35m) centres vertically. Their function is often debated. Is it needed to stiffen the wall against a concentrated load, to fix the wall lining, to prevent the studs...
I know of a builder (here in Australia) who built all his roof frames on the concrete slab on ground. He installed all the concrete roof tiles except for a few and installed long-stroke hydraulic jacks (the jacks poked through the missing tiles) and raised the lot in one go. THEN he installed...
Of course you can't believe all you read on the Internet (Sweden's changeover was 1967 not 1969).

seems somewhat of an authority on the subject (after 1920 for half of Canada and about 1800 in USA).
Let me add that I understand that Napoleon precipitated the change along with many notable improvements (like street numbers). Horse drawn traffic travelled on the left as proscribed by the Romans. But of course in pre-revolution France those in carriages were the aristocracy. The poor...
It is interesting that you had many gauges in the USA as we had the same problem in Australia...but Mark Twain was not amused.
The following is an extract from the Victorian Railways Web site. It seems not dissimilar to the US experience
Early history
Australia's railways were developed in an...
Can someone enlighten me when the US & Canada changed from driving on the left to the right? (I understand that the US changed some time after the French Revolution.)
While I know you are looking for US examples there is an excellent collection of structural wood engineering information brochures called Informationsdienst Holz (German. One of these is Fachwerkbinder Berechnung Konstruktion dealing with what we call in Australia Architectural Trusses. Large...
As far as I know all Eucalyptus grown in South America have come originally from Australia. There are many species and the properties are in the Australian Standard AS 1720.2 ...available over the internet from Standards Australia. (metric standard)
You must know the species and the grading...

With regard to road signs, I was in Ireland the other month and many distance signs are Metric and some still imperial. The Metric are white on green, Imperial black on white.
No problem in the small Toyota hire car I was driving. All the display was LED... speedometer, odometer, trip...
Have done several designs based on the same principle but for bridge railings so not entirely applicable. Are you proposing that they fall flat on the ground or pivoted at the top? Is there a problem with the latter with a debris loading or a rogue log etc.?
Massey,
I was rambling about grads (an angular measure) not gradient (a slope akin to the Tan of the angle). It seems all those years at school learning about pennyweights, bushels, rods, guineas & fathings, chains, gram, litres (liters, see I can at least spell another language) reams...
Owg - We have split up the circle into 360 degrees basically since the Sumerians adopted a base 60 and as surveyors we split up the degrees by further 60 subdivisions (minutes) and again (seconds). We repeat this in organizing time (seconds and minutes again). So there could be an argument for...
I always thought that the imperial system was a better system especially when using units to the base 12 (inches and pound[currency]). It was easy to divide things between people for barter for instance (1x12, 2x6, 3x4)... but now we have grown beyond that using mathematics as a tool for many...
I have now accumulated 15 years of drawings. Sometimes I want to look up previous drawings on some problem but like many systems my drawing files are named with a job number and arranged in folders of the year of their creation. But my problem is that I want to find all the steel trussed...
Thanks for all the replies to my post.
Don't get me wrong I find QPRO 9.0 quite satisfactory and have been using it since version 3 (Lotus before that). My specific question is that I often find QPRO generates 'fatal' errors.... and QPRO doesn't translate Excel reliably. So I am considering...
My first post here, but from my quick look through and almost invariably Excel is mentioned. Am I a dinosaur still using QuattroPro for spreadsheeting? Is Excel relatively more stable than QPRO?
Try "Design of Laterally Loaded Piles" CIRIA Report 103 UDC 624.131.531.6. It gives a comparative evaluation of various methods including estimation of displacement. I guess your application is for short relatively lightly loaded piles.
