Deflection of Beams

Deformation of a Beam under Transverse Loading
Deformation of a Beam under Transverse Loading
A crucial component in the design of beams is the identification and measurement of deflection. A comprehensive understanding of deflections is necessary ...
Equation of the Elastic Curve
Equation of the Elastic Curve
The plane curve's curvature at a point on the curve can be expressed using an expression involving the curve's first and second derivatives. The ...
Elastic Curve from the Load Distribution
Elastic Curve from the Load Distribution
When a beam carries a distributed load, the shear force and bending moment at any point on the beam can be expressed in a differential form. A third-order ...
Deflection of a Beam
Deflection of a Beam
The deflection of a beam in a roof structure can be determined using the integration method, provided that a single analytical function can represent the ...
Method of Superposition
Method of Superposition
The method of superposition is used in structural engineering to calculate the slope and deflection of beams subjected to multiple loads. When a beam ...
Moment-Area Theorems
Moment-Area Theorems
The moment-area theorem provides geometric properties of an elastic curve for determining deflection and slope at any point on the beam supporting a ...
Beams with Symmetric Loadings
Beams with Symmetric Loadings
The Moment-area method can be implemented on a cantilever beam under a concentrated load and moment to identify the slope and deflection. The process ...
Beams with Unsymmetric Loadings
Beams with Unsymmetric Loadings
Analyzing a supported beam under unsymmetrical loadings requires a reference tangent with a known slope to identify the level point. The slope of the ...
Maximum Deflection
Maximum Deflection
Consider a train moving on a bridge. Here, an unsymmetrical load is applied to a supported beam where the maximum deflection doesn't usually occur in ...
