A compound shaft drives three gears, as shown. Segments (1) and (2) of the compound shaft are hollow bronze [G = 6,500 ksi] tubes, which have an outside diameter of 1.55 in. and a wall thickness of 0.1975 in. Segments (3) and (4) are solid 1.10-in.-diameter steel [G = 11,500 ksi] shafts. The shaft lengths are L1 = 78 in., L2 = 8 in., L3 = 25 in., and L4 = 25 in. The torques applied to the shafts have magnitudes of TB = 940 lb·ft, TD = 500 lb·ft, and TE = 100 lb·ft, acting in the directions shown. The bearings shown allow the shaft to turn freely. Using the sign convention presented in Section 6.6., calculate: (a) the magnitude of the maximum shear stress in the compound shaft. (b) the rotation angle of flange C with respect to flange A. (c) the rotation angle of gear E with respect to flange A.

The following tubular A36 steel shaft has an inner diameter of 25mm and an outer diameter of 35mm under the following loading condition. Determine the angle of twist of the end V. Consider: GA-36 = 75 GPa 1) What would happen if a solid shaft was used? 2) As a designer, do you recommend a solid or tubular shaft for the loading above? Why?

The gas storage tank is fabricated in the following manner: a 10-mm thick plate is rolled to form a cylindrical shell which is bolted on one side, then its ends are sealed by bolting two hemispherical shells. The resulting inner diameter of the tank is 4 m. All bolts have a diameter of 15 mm. If the internal pressure in the tank is 1 MPa, determine the following:a. the number of bolts needed in each hemispherical shell if the normal stress in the bolts should not exceed 250 MPab. the minimum required thickness of the hemispherical shells if the normal stress in the shell should not exceed 125 MPac. the hoop stress in the cylinderd. the minimum require spacing of the bolts in the cylindrical shell if the normal stress in the bolts should not exceed 250 MPa.

A compound shaft drives three gears, as shown. Segments (1) and (2) of the compound shaft are hollow bronze [G = 6,500 ksi] tubes, which have an outside diameter of 2.15 in. and a wall thickness of 0.1375 in. Segments (3) and (4) are solid 1.15-in.-diameter steel [G = 11,500 ksi] shafts. The shaft lengths are L1 = 62 in., L2 = 8 in., L3 = 25 in., and L4 = 33 in. The torques applied to the shafts have magnitudes of TB = 980 lb·ft, TD = 420 lb·ft, and TE = 170 lb·ft, acting in the directions shown. The bearings shown allow the shaft to turn freely. Using the sign convention presented in Section 6.6., calculate: (a) the magnitude of the maximum shear stress in the compound shaft. (b) the rotation angle of flange C with respect to flange A. (c) the rotation angle of gear E with respect to flange A.

A bolted connection shown is bolted with a A-325 bolts with an allowable shearing stress of 207 MPa. A-36 steel is used. The applied force "T" is equally divided among the bolts.
