Combined Normal Stresses An S3X5.7 American Standard I-beam is subjected to the forces shown in Figure The 4600-lb force acts directly in line with the axis of the beam. The 500-lb downward force at A produces the reactions shown at the supports B and C. Compute the maximum tensile and compressive stresses in the beam.
