An overhanging W920×449 rolled-steel beam supports a load P as shown. Knowing that P= 700 kN, a = 2.5 m, and o =100 MPa, determine (a) the maximum value of the normal stress om in the beam, (b) the maximum value of the principal stress omax at the junction of the flange and web, (c) whether the specified shape is acceptable as far as these two stresses are concerned.
