Question

explain the method of arch construction​

Answer 1

An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it,or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it.


Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture,and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures.
