Buildings

Most commercial buildings have flat roofs. It's cheaper and gives a place for AC and other mechanical things without taking space form inside.

An arch in which the internal forces are purely axial is called a linear arch.

Thwe understanding of a load bearing structural frame where a steel frame supports the entire weight of the walls

Frame works exaple like a building or a igloo somthing that a human has made

cars, houses, tall buildings, trees, spider webs, bicycles and many more.

Because they are not high and they cost a lot of electricity

Either the Eiffel Tower or the Statue of Liberty.

It was derived from the Greek 'Metron Katholikon' meaning a universal measure. The word gave rise to the French 'Metre' in 1797 and then passed into the English language

Probably because skyscrapers can hold more things than any other type of structure given the amount of area. Besides, would you rather go to an island with a hut, or a skyscraper?

Skyscrapers and tall-rated buildings uses glass for aesthetic and functional purposes. Transparent glasses gives a elegant look of the outdoor to the building users. Moreover enormous varieties of glasses are there... Each has its own and unique functional benefits. Reflective glass, solar-control glass, Fire-Resistant glass, Low-e glass, Self-Cleaning glass, switchable glass, tinted glass and much more...

(YMCA) also began in

Because she wanted to spend more time studying and working on her high school studies.

Wright, as described earlier, found freedom of construction and planning in cantilevered forms, especially those made of reinforced concrete. In this material steel rods join with cement and gravel, hardening into an amalgam of great strength, if properly fabricated. The cantilevered, horizontal elements of Fallingwater were cast in reinforced concrete and finished with a coat of matte, sandy, warm-tinted paint. Where necessary, the slabs were cast with extra rods and concrete, forming integral beams. The slabs may be considered in two ways, as floor and as ceilings.

You are apparently referring to the Cartesian system of assigning x, y, and z coordinates to map out the relationship of objects in space.

a point has to occur somewhere - and to define its location in two dimensions (like in a floor plan) you need to provide an x and a y dimension. If you want to describe the location of a point in three dimensional space you also need to provide a height above the ground - the z coordinate.

A line is simply the direct path between two points in space. Thus, to draw a line you need two points.

If you are asking how to measure these with a ruler, a point has no dimension. A line has only 1 dimension.

if it has a basement the cool air from there could be circulated and blown in to the upper half, or water could be atomized threw pipes ran from the celing and blown threwout the building

yep

A coombed ceiling is a ceiling which slopes downward.

they are made for many different reasons, but i think they are made to get a good view of a city.

maby too help with earth quakes.

Using pads minimises costs for the concrete necessary at the same time reduce excavation needed which you would usually use for pile, raft and strip foundations.

However they cannot take excessive weight such as a concrete office block or be used on 'fragile ground'

The Petronas towers reach a height of 1483 feet (452m) tall, which was the tallest building in the world at the date of its completion, measured to the highest point.

According to the State of Lousiana, pine wood is greater than 70 to 100 and inorganic particle board is 15 -20, therefore lower numbers are better. Please note that 20 seems to me to be close to 26, looking at various materials the difference isn't great. But 20 is more flame spread resistant than 26.

Interior zoning is the interior design technique of creating recognizable sub spaces or zones inside of large spaces through variations in sensory input, rather than using structural isolating features such as walls, ceilings and doors. It is accomplished by the application of unique materials, lighting, surfaces, textures, elevation changes, acoustics and even smell to differentiate the subspace from the rest of the whole space.
