WebMay 2, 2024 · The moment of inertia (second moment or area) is used in beam theory to describe the rigidity of a beam against flexure (see beam bending theory). The bending moment M applied to a cross-section is related with its moment of inertia with the following equation: where E is the Young's modulus, a property of the material, and κ the curvature … The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an See more For more complex areas, it is often easier to divide the area into a series of "simpler" shapes. The second moment of area for the entire shape is the sum of the second moment of areas of all of its parts about a common axis. This … See more See list of second moments of area for other shapes.

Information and translations of second moment of area in the most comprehensive dictionary definitions resource on the web. Login WebExpert Answer. Below is a deformable (prismatic) beam with a Young's modulus and second moment of area denoted as of E 1 and I 1, respectively. Beam AB is supported by rod AC with an axial stiffness of k2 ≡ E 2A2/L2. A measure of the stiffness of the beam is k1 ≡ E 1I 1/L13. Both k1 and k2 have units of [force/length]. memorial marathon okc 2022
