Question

3. Define true arch and double dome.​

Answer 1

Answer:

A dome (from Latin: domus) is an architectural element similar to the hollow upper half of a sphere; there is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.

A dome can rest directly upon a rotunda wall, a drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. A dome's apex may be closed or may be open in the form of an oculus, which may itself be covered with a roof lantern and cupola.

Answer 2

QUESTION :

• Define true arch and double dome.

ANSWER :

TRUE ARCH

• 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.

DOUBLE DOME

• A double dome is built of two layers. There is one layer inside which provides ceiling to the interior of the building. The other layer is the outer one which crowns the buildings. The devices of double dome enable the ceiling inside to be placed lower and In better relation to the Interior space it covers.
