When constructing structures, the most important thing we have to think about is gravity. Gravity Newtons third law of force states that for every force acting on a body, the body exerts force having an equal magnitude in the opposite direction. Columns are rigid structural components designed to support axial compressive loads. Long slender columns are subject to failure by bulking rather than crushing. when the proportion near the middle of a column buckles, the whole column fails. To avoid collapse, the weight must be equally distributed with at least four columns. That way, even if the weight and force is too high, the columns will reach equilibrium, and hold the weight.
