A parabolic arch is effective for uniformly distributed loads because it naturally shapes the load's distribution into a form that allows for efficient transfer of forces. The geometry of a parabolic arch enables it to evenly distribute the load along its length while minimizing bending moments. This shape also helps in maintaining structural stability and reducing material usage, making it a popular choice in architectural design for bridges and buildings. Overall, the parabolic form optimizes structural performance under uniform loads.

How do you draw parabolic and cubic curves in SFD and BMD?
Based on the given problem,parabolic and cubic curves are drawn in SFD and BMD.if the given problem has UDL(uniformly distributed load),then we get parbolic curve in BMD.if the given problem contains UVL(uniformly distributed load),then we get parabolic curve in SFD and cubic in BMD.
How does the number of arches in an arch bridge affect the load it can carry?
An arch is a curved structure with supports at each end to take up the load which is evenly distributed across the arch plane with the stress at the Linc pin block but distributed to the supporting pillars . The greater the length of the bridge the greater is the number of arches to have a distributed load.
What are udl loads?
Uniform Distribution Load Uniform Distribution Load
What are the Bending moment diagram for simply supported beam with udl?
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
What is the comparison between common arch and inverted arch?
The "inverted arch" is used when a sideways, or inward load, is to be resisted. The "common arch" supports a vertical load.
Why suspension bridge is a parabolic shape?
A suspension bridge exhibits a parabolic shape due to the way the cables distribute tension and load. When a load is applied, the weight of the bridge and any traffic creates a curve in the main cable, which ideally forms a parabolic arc. This shape minimizes the bending moments and forces acting on the towers and deck, allowing for efficient weight distribution. Additionally, the geometry of a parabola ensures that the vertical forces are evenly distributed along the span of the bridge.
What is concentric load and distributed load?
A concentric load is a force applied at a single point on a structural element, typically resulting in uniform stress distribution around that point. In contrast, a distributed load is a force spread over a length or area of a structure, causing varying stress along the length of the element. While concentric loads often lead to bending or axial stress, distributed loads usually result in shear and bending moments that need to be accounted for in structural design.
What is the Shape of bending moment diagram for cantilever beam carrying uniformly distributed load?
It is parabolic, or second order:M = q x squared/2An excellent software to view the profiles of Shear force & Bending moment diagrams.http://www.mdsolids.com/
How does a arch work?
An arch works by transfering the load on the central portion of the arch outward and downward into the columns which support it.
What is a distributed load?
A uniformly distributed load (UDL) is a load which is spread over a beam in such a way that each unit length is loaded to the same extent.
What is the bending moment diagram for a simple supported beam with udl and a point load not in the centre of the span?
The answer is not formulatic. There will be a parabolic shape from the dead load and a discontinuity at the point load.
What is couple load?
couple load is the combination of both concentrated and distributed loads.
