In terms of material support, what is the function of a rib?

A rib in engineering design primarily functions as a brace or support within a structure. Ribs add strength and stiffness to various components, particularly in applications like beams, panels, or surfaces that require reinforcement to withstand loads or stresses. By strategically placing ribs, engineers can ensure that structures maintain their integrity while minimizing material usage.

This is particularly important in aerospace, automotive, and architectural applications, where both weight efficiency and structural strength are critical. Ribs help distribute forces evenly across a surface, preventing failure by enhancing the overall load-carrying capacity of a design element.
