![]() If bending stress exceeds the materials yield strength it will be permanently deformed and not return to its original shape.Ĭalculate the deflection of hollow rectangle and its bending stress.ĭeflection = 4.938271604938271e-9 (Inches)īending Stress = 0. This online Mechanical Engineering Calculator is to compute the deflection of hollow rectangular beams. In the equations for axial stress and transverse shear stress, F is the force and A is the cross-sectional area of the member. ![]() They are also resistant to torsional forces, much more so than I-beams. ![]() MI for hollow rectangle beams = (Width * Height 3) - (Inside_width * Inside_height 3) / 12ĭeflection = (Length 3 *Force / (3 * E * MI)īending Stress = (Force * Length) / (MI / (0.5 * hHeight)īuilders use hollow rectangular beams in construction because such beams can withstand the forces of shearing and bending in both the x- and y-directions.
