The strength of the concrete is given by f' c = 4000 psi and f r = 475 psi. Bending of Homogeneous Beams For elastic analysis, the elementary equations from mechanics of materials is used: f = M y / I f = stress M= moment applied to the beam I = moment of inertia of the cross section y = distance from the neutral axis Example 3.1 Consider a plain concrete beam that is 10 inches wide and 30 inches deep.
