Cantilever beam geometrical parameters such as, dimensions, volume, weight, and material play significant role in defining the beam function and where it might be used. The present study is to obtain optimal cross section dimensions of a hollow square cantilever beam subjected to static load in order to accomplish the ideal structure with minimum weight and maximum strength. Commercial finite element software (ANSYS R17.2) was used for simulating the hollow square cantilever beam made of steel subjected to static load at free end and supported at the another end. Design Optimization technique was used to investigate the effect of cross-sectional dimensions such as height, width, thickness and filet radius of flange; on beam weight in order to withstand the exerted load yet with minimum material keeping the total equivalent stress just below the maximum yield stress,(σy<250MPa). Maximum equivalent stress, geometry mass and total deformation are changed (reduction) in about 30.75%, 22.89% and 67.45% respectively.
