how much does 1/2" steel weigh per foot?

that depends on what kind of steel.  Not every steel is made the same way or with the same density so it varies.  I can tell you that a W14X56 is a 14" wide flange beam and weighs 56 lb/ft

Do to the increased weight (volume) I'd say 1/100th of 33 feet.

It can only hold the weight of 16 pennies.  He-He.  Just kidding.  Actually, that's a good question.  I've been a carpenter all my life and to tell you the truth, a 16d nail is one damn strong piece of metal.  Ever pull one out of a piece of lumber that was shot in with an air gun?  It'll make you grunt, that's for sure!  One that's galvanized is even more difficult.  And if it's a ring-shanked nail?  Forget it.  It's in the lumber until the wood rots.  It's really not a matter of how many pounds it can hold.  It's a matter of its bonding power.  You can bend a 16d nail quite easily, but after it penetrates into a 2 x 4, for example, it's meant to stay, depending on how it was put to use "structurally".

There are some charts on:\nhttp://www.krausco.biz/tonagechart.html\n\nwhich give a tonnage based on several factors. Once you have a method for actually calculating, you could check your answer against this site:\n\nexerpt:\n"RULE OF THUMB formula for making multiple bends on a press brake. For shape shown, in mild steel with radii equal to metal thickness unless otherwise noted.\n\nMultiply Metal Thickness by factor = Tons per Foot\n\nExample for bottom bending\n16ga (.062) Mild Steel. .062 x 150 = 9.3 tons per foot."\n\nHope this helps!

The density of wrought iron is 7.8 g/cm3 which translates to 7,800 kg/m3.\nHot dip galvanizing is a process by which steel is dipped in a zinc bath and coated to prevent rusting. Steel dipped in this process will gain about 6% weight.

foot pounds, 1 foot pound is the amount of force it takes to move a mass of 1 pound a distance of one foot. A newton is the equivalent measure in the metrc system.

One US ton is 2000 pounds. Now what was the question?

The density of glass is around 2.3 gm/cc or 0.85 lb/in^3.  To get the  pounds per square foot,  Multiply the thickness in inches by 12.  So a 1/8" thick piece weighs 1.5 pounds per square foot.

ventoris was right on, except for the weights listed.  Tungsten is a heavy, dense metal, characteristics good for darts.\nWeights, however, vary based on whether throwing steel tip or plastic tip.  Weights for steel tip are obviously much higher - up to at least 30 grams.  I don't believe you can get steel tips as light as 16 grams.  \nCorrect, though, that weight is purely personal preferance.  a good range for steel is 22 - 24 grams.  I have found many beginners like the darts heavier with a bigger barrel.  The big barrel makes the darts easy to hold and the extra weight makes a consistent trajectory somewhat easier to obtain.  Fine control of location is usually harder to achieve, though.

If you have a seesaw let's say and you place a 100 Lb weight on one end and push down the other end to raise the weight one foot, your "machine" has done 100 ft-lb of work.  You should expect to get 100 ft-lb of work back out of the machine as the weight drops one foot to its original position.  However, if the bearings at the pivot are let's say badly rusted and you have to push down 200 lbs to rais the 100 lb weight the machine is inefficient and when the 100 lb weight drops again perhaps it exerts only 50 lb force at the other end.  If you divide output by input and multiply by 100%, you can calculate the machine's efficience.  In our examples:\n\n     output/inputx100% = efficiency\n\n     100/100x100% = 100%  (frictionless machine)\n\n     100/200x100% =  50%  (rusty work in)\n\n      50/100x100% =  50%  (rusty work out)

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