You have to support the structure (the actual arch) using a wooden form up to the point where you insert the keystone, after which the arch will be self supporting.

Fibre reinforced plastic is often used in construction, automotive, marine and aerospace. It's made of a polymer matrix reinforced with fibres. Some examples of those fibres are glass, aramid, carbon and basalt.

These are very unique screw drivers, made for low access screws. In my experience, the most common use for these are installing the screws on door knobs. The handles protrude into the path of the screws, so these offset screw drivers allow you to secure the fasteners without scratching the finish of any door knobs.

As pozzolan greatly improves the strength and durability of concrete, the use of ash is a key factor in their preservation and add to the concrete's final strength and increase its chemical resistance and durability.It can also increase workability of cement while reducing water demand. The replacement of Portland cement with fly ash also reduces the greenhouse gas foot print of concrete, as the production of one ton of Portland cement produces approximately one ton of CO2. Since the worldwide production of Portland cement is expected to reach nearly 2 billion tons by 2010, replacement of 30% of this amount by fly ash could dramatically reduce global carbon emissions.

The Statue of Liberty is made of copper supported by an iron skeleton. "179,200 pounds (81,300 kilograms) of copper was used in Statue. 250,000 pounds (113,400 kilograms) of iron. Total weight of the Statue is 450,000 pounds (225 tons). The thickness of Copper sheeting is 3/32 inch (2.37mm), about the thickness of a penny. "

I think I found the answer elsewhere in the Net: Rodabanca in English may be: Skirting, Backsplash, countertop skirting, countertop skirting edge, countertop backsplash. See http://www.freepatentsonline.com/6135581.html, http://www.dallasgraniteinc.com/BackSplash.aspx, http://www.schluter.com/media/datasheets/schlueter_db_wall_us_0806.pdf "Backsplash" is used for taller protective cover of back countertop walls, frequently works of tiling art. "Skirting" seems to be more colloquial, at least internationally.

Limit state design is designed a concrete member for its various damage limit states, concrete sover spalling, steel yielding all the way up to the crushing of the concrete core, with this you can control how you want the concrete member to fail.

This is a Microsoft network driver and may be used with certain types of tunneling software. Internet Connection Sharing can install this driver depending on the version of Windows. This driver is used to link multiple network adapters together at a much lower network layer. If you have ever had Internet Connection Sharing on this computer and no longer use it then you can safetly delete this network connection. Depending on what version of Windows you are running there are different ways to do it.

A zero bar is a bar in a truss that supports no load but is only there for the stability of the structure

There is no age limit on learning! If you have been away from education for a long period (and at age 40 you probably have) or if you have non standard qualifications then it may be sensible to study a foundation course but this may or may not be mandatory depending on the institution at which you wish to study.

Only if you seal the well off from the water table. Otherwise you will have to put enough water in the well to raise the water table 30 meters.

A well can be filled-in using earth or a mixture of earth and "safe" material such as clean broken bricks, etc. If anything is used which could poison or otherwise contaminate the water table that would be dangerous and probably illegal too. (It depends what your local Environmental Protection laws say.)

Just by using water from somewhere else it is impossible to say if the well shaft could be filled to the top - that is like asking "What is the length of the string in that ball of string?" Unless you made the ball yourself, from a known length of string, or it says the length on the manufacturer's label, you can only find out the length of the string by unwinding the whole ball and measuring the length of the string!

Bear in mind that the well might be fed from water-bearing rocks or from an underground cavern with a lake in it. You might try pumping-in many thousands or millions of gallons of water and would still not be able to fill the well - so don't ever plan to raise your local water table just by pumping water into it! The position of the water table is a natural phenomenon, it results from the location of aquifers (water-bearing rock layers), the height of the site above average sea level, etc. In short it all depends on where the site "is" within its surrounding the terrain.

So, as the first part of the other response to this question says, the is "Yes, but only if you seal the well off from the water table." If you do that you will in effect be creating a tank to hold water that you put into it from somewhere else: rainwater or water from a mains supply using a hosepipe, etc. That tank will then hold the new water above the existing ground water table.

If the question is asking how the water down at the bottom of the well can be brought to the surface, the is "Yes, but only by using something to lift the water up to ground level." The old-fashioned way to do it is to drop down a bucket on a long rope so you can haul up the bucket full of water. The modern way is to use a "lift pump".

Water cannot be raised using a suction pump from 30 metres (100 feet) below ground level. The maximum height you could raise water using a suction pump depends on the water temperature and the atmospheric pressure at the site. For most places on Earth the greatest height it is possible to raise water using a suction pump is usually reckoned to be just under 9 metres (30 feet).

Why is that so? If the water temperature was well above freezing, say 20oC (68oF) and the atmospheric pressure was, say, 1 Bar (= 1000 milliBars) then the pressure present underneath a column of water about 9 metres (30 feet) high would be the same as the pressure of the atmosphere. So that height is just a bit more than the maximum practical height you could raise water using a suction pump. If you tried to raise the water any higher all you would be doing is creating a vacuum in the pipe!

It is very important. Incorrect conclusions can be reached when the sample does not represent the underlying population. Experimental studies frequently go to great lengths to insure an unbiased sample. In observational studies, the statistician may identify factors which could make his sample not representative of the population. I will give you a real example. The US Fish and Wildlife Division conducted a study of the area that Florida cougars roam the Everglades. They tagged and tracked the movements by GPS. By using only daytime data in their computer models, a time when the cougars were more likely to sleep, they underestimated the distance the cougars could roam. You may be able to find many examples of biasing the data, either at the collection stage or later culling out certain data (as was done in the cougar example).

It is the one in which tensile stresses in the concrete are entirely obviated at working loads by having sufficiently high pre-stress in the member.

Spandrel glass is made by coating a vision glass with an opaque coating. The is prevents people from looking through the glass and seeing structural features inside the building. Spandrel glass is most often used in curtain wall construction where the glass and aluminum framing on a multi-story buiding passes on the exterior side of the floor slabs. A typical high-rise building will have a top-of-slab to top of slab distance of about 12 feet, but the slab-to-ceiling height is usually 8 feet. The 4 feet above the suspended ceiling contains the "spandrel beams" (the beams that hold up the floor slabs), electrical wiring, plumbig, mechanical ducts (heating and air conditioning) and fire suppression systems. Since most of these items are rather ugly, spandrel glass is used to high them from public view. Spandrel glass is not intended for use in a "vision glass" area. If you look at spandrel glass from the interior of a building looking out toward daylight, you will see pinholes and variations in the density of the coating.

please, the real answer! no 'the Aztecs got help from aliens', cuz aliens DO NOT EXSIST!!!! ESPECIALLY BACK THEN! (no ads, plz).no random answers like '78 years' or '55 years' or '50 years' or '3 weeks cuz they got help from aliens' the REAL ANSWER!!!!!! please, the real answer!!!!no silly answers, i really want to know how long it took!! i am NOT kidding!! please!!

Don't try it without having an architect engineer it for you first. Trusses are an engineered product. If the integrity of the truss is compromised you might have some serious problems.
