Assuming the concrete is uncracked, compute the bending stresses in the extreme fibers of the beam at M = 275 kN-m. Determine the cracking moments for the sections shown if f'c = 28 MPa. Compute the flexural stresses in the concrete and steel for the beams shown using the transformed- area method at M = 275 kN-m.
