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].

Web15 Jul 2024 · Second moment of Area/ Torsional constants are calculated with respect of a given axis and if the axis changes, these parameters should change. I dont understand why these parameters are not changing. I intend to place my sketch of cross section about desired axes so that they parameters are calculated with respect to that axis. WebThe Second Moment of Area is a geometrical property of a beam and depends on a reference axis ( which is in the plane of the area). The smallest Second Moment of Area about any axis passes through the centroid.
