Beams are the extended members of a structure that carry the loads brought by the horizontal slabs of the structures like solid concrete floors, wooden floor joist systems, and roofs. Consider a simply supported beam of length L = 10m with a uniform load (force per unit length) of w = 5 kN/m acting on it. We can define the stiffness of the beam by multiplying the beam's modulus of elasticity, E, by its moment of inertia, I.
