Question

5. H I steel barstock is loaded in tension and Cross section in bending. Draw Mohr's circle at points 1 and 2 at the midspan of the beam, following these steps: 120 lb 2 in. [a] Calculate the weight per unit length of the bar. [lb./ft. Draw complete shear and moment diagrams, including the 120 lb. point load and the beam weight, to find V and M at the midspan. 5 ft. 5ft Ib] e] Calculate the bending stresses at both points. [psi) Id] Calculate the tensile stress due to the axial load, and add it to the bending stresses from part c.Epsi [e] Calculate shear stresses at both points due to the bending load. [psi] [f] Draw Mohr's circle for points 1 and 2, and calculate σ', σ2,0, and-n.

axial stress equals 0
