Assuming the concrete is uncracked, compute the bending stresses in the extreme fibers of the beam of Figure 2.5 for a bending moment of 25 ft-k. The normal-weight concrete has an f of 4000 psi and a modulus of rupture f, =7.5(1.0)/4000 psi = 474 psi. Determine the cracking moment of the section. %3D %3D
