A sector is a triangular slice to the center of a circle (like a slice of pie). Use the slider to change the value. In the field ofÂ structural engineering, the second moment of area of the cross-section of aÂ beamÂ is an important property used in the calculation of the beam'sÂ deflectionÂ and the calculation of stress caused by a moment applied to theÂ beam. This Calculator calculates area of Hollow Square from Length & Thickness.A plane figure with four straight sides and four right angles, especially one with equal adjacent sides, in contrast to a square with hollow at some thickness. Specifically, the relationship between applied bending moment and normal stresses is given by the formula: When normal stresses are negative, it means they are compressive, while positive normal stresses are tensile. I_x=I_y=I is applied around centroidal axis x, the section will respond with normal stresses, varying linearly with the distance from the axis, assuming the material is linearly elastic and the beam flexural behavior follows the simple beam theory (known as Euler-Bernoulli beam theory). .
