Which is the longest Setu in India? It is not a catenary. The hydrostatic pressure is uniform for a given depth plan section and is normal to the surface of the dam. This generally means that at only one point in the section will it be normal to the section. The dam structure in this case is an arched gravity dam, so both the sheer mass of the structure and the load transfer to the walls of the canyon are important.
In a pure arched dam of negligible thickness and insignificant height, the shape of a plan section would be a segment of a circle. One of the major contributions of Brunel was proving analytically that a semi elliptical arch can also work. An arch is not a specific shape; it is a structure spanning some distance, that carries the vertical loads primarily as internal compression due to its shape and the way it is supported. That is all. The shape may be catenary, half-circle, semi-elliptical, korbbogen, you name it, but these are all arches.
Some of these are optimal compression only for a certain kind of loading: catenary for pure vertical loads, circular for hydrostatic pressures and so on.
You can build a really slender structure if the main component of your load corresponds the chosen shape. That is why steel arch bridges are often chosen in the meter span range. However, if the load deviates from the optimal — say only half side of the arch is loaded — the performance of the structure is abysmal, as the external loads can only be balanced by internal bending action, for that a slander structure is not well suited.
Llama on wheels! There are several reasons. The invention of the wheel for transportation purposes occurred around the fertile crescent area because you had a big oasis surrounded by deserts — trade happened over long distances along relatively flat areas where you could ride chariots and pull carts. In the Americas, the Aztecs, Olmeks etc. Another thing for the Aztecs in particular is that they built their stoneworks around areas prone to sinkholes and earthquakes — the ground was soft, so when they built something they just piled a ton of stones and rubble as a foundation until it stops sinking.
When they built new temples and monuments, they built them on top of the old ones with proven foundations. And the important pre-requisite for pulling loads with a wheeled cart: tame draft animals. Middle east had horses, oxen, cows… basically large domesticated animals that were tame enough and strong enough to be harnessed for pulling carts. Yeah probably.
They probably knew how to master nuclear fusion as well, too bad they had no use for it. Only if one side is deformed a triangle loses its shape. Triangle is most stable structure. My answer would be a triangle in 3D its a pyramid.
Triangle is the most stable shape. Triangle requires less of material and more stability. The weight presses down on the arch and is spread outward along the curve to the ground below.
The weight causes the top two sides to squeeze together and the bottom side to pull apart. The weight caused the top side to bend too much, so it failed! When an arch is pushed too hard, the sides spread apart and collapse. Are triangles the strongest shape? They are according to the buzz on the Internet and most stable too , despite competition from circles. Mythbusters even proclaim that "triangles are the strongest shape because any added force is evenly spread through all three sides".
In terms of three-dimensional shapes , the sphere, ellipsoid an egg shape and dome are able to withstand the most outside pressure. The arch contained within these three is stronger than a flat surface. A structure which will not topple over easily when acted upon by a load is said to be stable. It is more difficult to make a structure with a wide base topple over so, the wider the base therefore, the more stable the structure. The shape and the material used to built a structure determine its resistance.
A true arch is composed of wedge-shaped blocks typically of a durable stone , called voussoirs, with a key stone in the center holding them into place. In a true arch , weight is transferred from one voussoir down to the next, from the top of the arch to ground level, creating a sturdy building tool.
In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers. The beam itself must be strong so that it doesn't bend under its own weight and the added weight of crossing traffic. The higher the arch , the stronger and thicker the walls need to be, and walls could only be so thick before becoming ridiculously impractical and expensive.
Pointed arches , however, direct much of the thrust of weight downward, toward the ground, and they can thus support much thinner, higher walls.
