Beam (structure)
A beam, or structural beam, is a structural member that carries loads applied transverse to its long axis, resisting them primarily by bending, or flexure.
Bending
Bending is the behavior of a slender structural element, such as a beam, under a load perpendicular to its axis, stretching one surface while the other compresses.
Bending moment
The bending moment is the internal moment a loaded beam must transmit at a cross section to stay in equilibrium, a standard calculation in structural engineering.
Deflection (engineering)
In structural and mechanical engineering, deflection is the displacement of a structural element such as a beam or column under load, calculated with Euler-Bernoulli beam theory and capped by building codes as a fraction of span.
Euler–Bernoulli beam theory
Euler–Bernoulli beam theory, also called the engineering beam theory, is a mathematical model for beam bending, developed around 1750 and still standard in structural engineering.
Flexural strength
Flexural strength, also called modulus of rupture or bending strength, is the maximum stress a material's outer surface sustains before it yields or fractures in a bending test.
Second moment of area
The second moment of area, also called the area moment of inertia, is a geometric property of a cross-section that measures its resistance to bending.
Section modulus
The section modulus is a geometric property of a beam's cross-section, defined as moment of inertia divided by distance to the outermost fiber, that measures bending strength.
Shear and moment diagram
A shear and moment diagram is a pair of graphs plotting internal shear force and bending moment along a beam, used to locate potential failure in design.
