2. Now consider the same beam when a 60-inch-long rod is added at mid-span. The rod's cross section area is 0.75 in². Find the axial stress in the rod, draw the shear and moment diagrams for the beam, and find the maximum stress in the beam. (Intermediate Result: Axial Force in Rod= 7,885 pounds.)

For both problems, the beam is a W8 X 31 (1 = 110 in4, c = 4.0 inches)
section, and the beam and the rod are A36 steel (E = 29 X 10
psi).
