The beam equation contains a fourth-order derivative in . To find a unique solution we need four boundary conditions. The boundary conditions usually model supports, but they can also model point loads, distributed loads and moments. The support or displacement boundary conditions are used to fix values of displacement () and rotations () on the boundary. Such boundary con… WebbEquibiaxial loading consists of equal amounts of tension in both the \(x\) and \(y\) directions.

WebbBeam shear stress equation. Beam Shear is the internal shear stress that occurs on a beam when it is subjected to a shear force. Where, τ = beam shear stress. V = shear force. Q = static moment of the area (which is the summation of all areas multiplied by the distance from a particular axis) I = second area moment of the cross-section. WebbE = modulus of elasticity, psi or MPa. I = second moment of area, in 4 or m 4. L = span length under consideration, in or m. M = maximum bending moment, lbf.in or kNm.
