what's the diameter?  I don't know what class 2 means.

It varies between weights. Anywhere from 25-32, most likely.

the answer is 1.502 lbs/ft\n\nhttp://www.sizes.com/materls/rebar.htm

One line answer due to adhesion force between cement and wall.

If a weight is hanging from a V formed by two ropes, the angle of the V cannot be 180 deg, unless the weight is 0.\n\nThis is because the Tensions in the two ropes must compose to a force equal and opposite to the weight, which is acting vertically down.\n\nIf the angle is 0, then each tension is half the weight = 500/2 = 250 N\n\nFor any other angle, we need to know the relative lengths of the ropes.  If they are equal, the tensions are equal and\n2Tcos(a/2) = weight.\nwhere a is the "V" angle.

The large round bales typically weigh around a 1/2 of a ton (i.e. 1000 pounds).  Rectangular bales weigh around 60-100 pounds, depending on the moisture retained.  Assuming an average of 80 lbs or so, it would take 1000/80 = 12.5 bales to equal one large round bales.  Of course this is all approximate.

1650 lumber has a specific gravity of about 0.42.  This means its density should be close to 26.19 lbs/ cu. ft.  The one foot 2x4 should weigh 1.46 lbs.

An eight foot railroad tie will weigh between 140 and 170 lbs. Sometimes even more if it has absorbed a large amount of creosote.

assuming 1.39/lb.\nit would take 7.5 lbs.\nso it would cost $10.43

probably 2-5 grams.  it depends on the dimensions of the ballon.  you might as well ask a question like "how long is a piece of string?"

Between 140-155 pounds

between 25 and 45 pounds

There is no specific weight...it is your choice BUT the lighter the better!

Your best bet is to measure out 40 yards and just do it!

I think it's around 110-130 pounds

You're talking about weight of steel tubing in lbs. per foot, which is\n10.6802   X  Wall Thickness X  ( Diameter - Wall Thickness ),\nand for Round Tubing it is 10.6802 x T x (OD - T), where OD is Outside Diameter. The websites I listed below just offer the formula, with no explanation for the constant, but I'll try to give it some explanation.\n\nThe constant must be related to the properties of the material in question, steel in our case, which is made of carbon and iron. The concentration of these depends on the application and it causes the weight to vary, consequently, the constant will vary also.\n\nThe 10.6802 must be the constant of weight (if we have to put a name on it) for commercial piping steel, and its units should be lbs/ft, so that you will get pounds in your result. I’m not a mechanics or materials engineer so I’m just putting the basics of material’s science to work here.\n\nI recommend you look in The Science & Engineering of Materials, by Donald R. Askeland, Pradeep P. Phulé, or any other materials book.
