Remember this!

Beam and joist are both important structural elements used in construction and engineering. However, they differ in terms of orientation, function, size, placement, and usage. Beams are horizontal elements that support weight and transfer loads, while joists can be either horizontal or vertical and are specifically designed to support the floor or ceiling. Beams are larger and wider, placed at regular intervals, and commonly found in larger structures, while joists are narrower, closely spaced, and more commonly used in residential or smaller commercial buildings.
