Solve all problems using the finite element stiffness method.For the beam design problems shown in Figure P4–31, determine the size of beam to support the loads shown, based on requirements listed next to each beam.

Design a beam of ASTM A36 steel with allowable bending stress of 160 MPa to support the load shown in Figure P4–31. Assume a standard wide flange beam from Appendix F, or some other source can be used.
