Wouldn't be nM would it? Newtonmeters ?\n\none footpound equals  1.3558179Nm

While every fastener has a specific required torque value, in the real world it's somewhat easier than that.  Generally speaking, the only fasteners that exact torque is critical are the head bolts/nuts, rod bolts/nuts and main bearing cap bolts/nuts.  Again generally speaking, all other fasteners can be safely torqued using good old fashioned common sense.\n\nThat being said, if a shop has the money to purchase basic hand tools to accomplish said work, there is no reason not to have at least one inexpensive torque wrench on hand.

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!

ya torque=f*d and since the distance is zero because the applied force is at the moment of inertia... Troque is zero! bahahaah oy i hate statics.. or physics.. same thing

Do you mean size? As a rule of thumb for bolts made to SAE standards in inches or fractions of an inch. You take the nominal size of the bolt, multiply by 1.5 and add a 1/6"  For metric you are on your own.

What you are likely looking is W=F*D \n\nWork = A Force * A Distance\n\nCheck out wikipedia for additional help:\nhttp://en.wikipedia.org/wiki/Mechanical_work

All you need to know to convert N*m to lb*ft is to know that they are both units of torque. Sure, you could say they are both units of length multiplied by force, but that's besides the point. To do a conversion you will need to convert between units, that's just a fact of the matter. Why convert more units then necessary? If you know they are both units of torque, you are already done. Look up the conversion factor and there you go.\n\n1 N*m = 0.737561 lb*ft

IMA assumes 100% efficiency, that no energy is lost. IMA = Distance in / Distance out\nAMA = Force in / Force out. takes into account energy lost due to friction

None. It takes no power to maintain that speed (on level ground, no friction). The object has kinetic energy (0.5 * m * v^2). Power was required to put it in motion and power can be recovered by decelerating it. If you do the math, the energy is 3551.86 ft-lb, equivalent to 1 horsepower for 6.458 seconds. Answer 1 neglected the fact that weight must be converted to mass by dividing by g, and energy is proportional to v^2.

The CG of the stick and the weight together is at the22.4 cm mark, because it is balanced when supported at this point.\n\nIf the CG of the stick were at x cm mark, the torque due to the stick at the 22.4 cm support\n\n134 g * (x - 22.4)\n\nThe toruque due to the 142.3 g weight at the support\n\n142.3g*(9 - 22.4)\n\nThe total torque must be 0:\n\n134 g * (x - 22.4) + 142.3g*(9 - 22.4) = 0\n>>\n134x -134*22.4 + 142.3(-13.4)=0\n>>\nx ~ 36.63 cm

Bound's hubby here:\n\nA grain is a very precise unit of measurement. a grain is 1/7000th of a pound ... 7000 grains to a pound.\n\nIn rifle and pistol ammunition, the bullet weight is expressed in grains, as is the powder charge. For example, a typical .308 Winchester target round would be a 168 grain Sierra MatchKing loaded on top of 41.5 grains of Accurate Arms 2520 powder.

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

Go to a McDonald's restaurant and ask them for a "Newtoner", that is a "Quarter Pounder" hamburger in metric. A "newton" (from Newton's Law) is a unit of force or weight and is about equal to one quarter of a pound - not often used. It is not the unit of mass, which is the "kilogram" in metric, and is what is normally used. It is the opposite in the British system (used here in the U.S. but no longer used in Britain) where the official unit of mass is the "slug" (hardly ever used) and the unit of force or weight is the "pound". They say the density of air, for example, at standard conditions is 1.2 kilograms per cubic meter - which is correct terminology - but then say it is also equal to 2 pounds per cubic yard - which is incorrect terminology but nice and accurate and easy to remember. One million tons of air, really 62,161,994 "slugs" in correct terminology, occupies about one fifth of a cubic mile in volume over, say, a farm field but is much easier to think about even so and compare to the weights of large ships, etc.

In what position is the bolt and what are the bolt's physical dimensions? If the bolt is laying in a horizontal position, and it's 1.60 cm thick (16 mm or about 5/8"), I'd say that the oil's refraction index is 1.00.\n\nOTBPOC
