11-10. Investigate if the W250 × 58 shape section can safely support the loading acting on the overhanging beam. The beam is made from steel having an allowable normal stress of Gallow = 150 MPa and an allowable shear stress of Tallow= 80 MPa. 118 40 kN/m 4 m Probs. 11-9/10 N m 50 kN

Find the max normal stress (?_???) of the beam below.

5-83 The A-36 steel shaft is made from two segments: AC has a diameter of 0.5 in. and CB has a diameter of 1 in. If the shaft is fixed at its ends A and B and subjected to a uni- form distributed torque of 60 lb in./in. along segment CB, determine the absolute maximum shear stress in the shaft. 5 in. 0.5 in. 20 in. 60 lb-in./in. 1 in. B Prob. 5-83

6-80* A steel shaft is loaded and supported as shown in Fig. P6-80. Determine the maximum allowable value for the axial load P if the maximum shearing stress in the shaft is not to exceed 60 MPa and the maximum compressive stress in the shaft is not to exceed 96 MPa.
