I am with you Russ,
ERW has a number of advantages, Easy to fabricate, no special techniques, economical, easy to repair, readily available. Why bother with anything else to make things complicated.
the "strength" of a column or strut under axial loading is in no way dependant upon the strength of the material in compression, but only on its geometry and the stiffness of the material ( modulus of elasticity)
An individual member made from chromoly is no stiffer in compression than ordinary...
from the bottom or top ball joint on the upright and at 90º to a line drawn thru the chassis pick up points will be close enough. The width of the A arm will not affect as long as it is on the same line
you nead to compare the section modulus to get a true indication.
a circular tube of the same thickness and same dimensions I.E. 25 dia as against 25 square
will be stronger in all respects save for bending.
A square tube of same dimension will be thinner to achieve equal mass and may not...
I cant see what the problem is, this site was setup by Ron for the exchange of information between like minded individuals pursuing a common goal, building cars. When I joined the site several years ago It was pretty clear that it was not a site for "selling stuff."
Advising someone where to...
Fantastic Mark,
having been involved in the design of borehole drilling rigs some years ago I had a lot of dealings with Hydrogeologists, I know what you are on about,great stuff
Stephen,
it is probable that the track sound level meters will be on A weighted frequency, A weighted is more universally used than C weighted. The A and The C refer to frequency filters. You should also have your SLM set on fast response.
The track noise limit specified should include the...
de-mineralised water, not distilled water is a better choice.
Good auto parts places should have it or suppliers to coffee shops as it is used in espresso machines, or perhaps Cosco or similar.
Concentrated anti freeze rather than pre-mixed coolant as it contains water that is not necessarily...
Al,
water as it turns to ice has max expansion at 0 º C , it is also becomes less dense at about 9% less than water, hence ice floats on water. Ice melting into water regains max density at 4 º C ( SG = 1)
Not heroes, we were just doing our job in what proved to be a senseless action in the end.
There were many who deserved that status however.
It was a long time before it was recognised as a military action in my country.
the much maligned helicopter was no better sight to guys on the ground and the distinctive sound of the UH-1 teeter-totter rotor system was music to their ears as they were about to be extracted from hell. Dont knock em nothing else could have done the job in lessening the casualty count.
very common item in OZ from the early 80's used by wholesalers to ship consolidated orders of small parts. Mainly used by hardware wholesalers, very smart lid on them, and stackable full or empty
