Webb5 jan. 2024 · Bending equation is considered to be a subsection of the bending theory. Bending theory states that a beam can undergo deformation when there is an external application of any form of force perpendicular to its longitudinal axis. Bending theory is also known as flexure theory. It basically signifies the effects of force on a beam.

"Webb14 apr. 2024 · To analyse this, the concept of pure bending is applied such that the internal reactions developed on any cross-sections are considered to be by virtue of bending effects alone. The normal and shear force are considered to be zero on any cross section that is perpendicular to the longitudinal axis of the member. i.e., F=0, " - Theory of pure bending
