"Radial" refers to a pattern or arrangement that radiates outward from a central point. This term is often used in geometry to describe shapes like circles or spheres, where all points are equidistant from the center. In design, radial symmetry creates a balanced and harmonious look, making it visually appealing. In engineering and mechanics, "radial" can describe forces or movements that occur in a direction that spreads out from a center. For example, in a radial engine, the cylinders are arranged in a circular pattern around a central crankshaft, allowing for efficient power distribution.
