A three hinged arch is generally hinged at its supports and
A. At one quarter span
B. At the crown
C. Anywhere in the rib
D. None of these
Answer: Option B
Solution(By Examveda Team)
A three-hinged arch is a structural form used in civil engineering to efficiently distribute loads and resist bending moments. It consists of three hinges, which allow rotation at the supports to accommodate the arch's deformation under load. The three hinges are located at the supports and at the crown of the arch.The crown of an arch refers to the highest point along the arch's curve, where the arch is subjected to compressive forces. Placing a hinge at the crown allows the arch to rotate and adapt to changes in loading and deformation. This rotational flexibility is crucial for the arch's stability and ability to carry loads without excessive stress.
Note: Options A, C, and D are not accurate descriptions of the typical hinge locations in a three-hinged arch. The correct configuration involves hinges at the supports and at the crown to ensure proper load distribution and structural performance.
