- : A hollow, pressurized sphere having a radius r = 4.8 in, and wall thickness t = 0.4 in. is lowered into a lake (see figure). The compressed air in the tank is at a pressure of 24 psi (gage pressure when the tank: is out of the water). At what depth D0will the wall of the tank be subjected to a compressive stress of 90 psi?A steel riser pipe hangs from a drill rig located offshore in deep water (see figure). (a) What is the greatest length (meters) it can have without breaking if the pipe is suspended in the air and the ultimate strength (or breaking strength) is 550 MPa? (b) If the same riser pipe hangs from a drill rig at sea, what is the greatest length? (Obtain the weight densities of steel and sea water from Table M, Appendix I. Neglect the effect of buoyant foam casings on the pipe.)The hollow drill pipe for an oil well (sec figure) is 6,2 in. in outer diameter and 0.75 in. in thickness. Just above the bit, the compressive force in the pipe (due to the weight of the pipe) is 62 kips and the torque (due to drilling) is 185 kip-in. Determine the maximum tensile, compressive, and shear stresses in the drill pipe.

If the shaft is turning at 100 rpm, what is the maximum horsepower that can be transmitted without exceeding the allowable stress? If the rotational speed of the shaft is doubled but the power requirements remain unchanged, what happens to the shear stress in the shaft?The stepped shaft shown in the figure isrequired to transmit 600 kW of power at 400 rpm.The shaft has a full quarter-circular fillet, and thesmaller diameter D1 =100 mm.If the allowable shear stress at the stress concentrationis 100 MPa, at what diameter D2 will thisstress be reached?

- An electric power transmission pole is 12 m above ground level and embedded 2 m into the ground. The butt diameter is 450 mm and the tip diameter (the top of the pole) is 320 mm. The weight of the pole, cross arms, and wires is 33 kN. Assuming the pole transmits the load as a point load, find the change in vertical stress in kPa at 1m depth.a shaft 80mm diameter transmits power at maximum shear stress of 63 mpa. find the length of 20mm wide key required to mount a pulley on the shaft so that the stress in the key does not exceed 42 mpa.A hollow tubular shaft will be used between the engine and the propeller of the boat as shown in the figure. The outer diameter of the shaft is d=74 mm and the wall thickness is t=6 mm. The power of the engine is P=10 kW and its speed is n=694 rpm. Accordingly, calculate the maximum stress on the shaft and show whether it is safe by drawing it to scale within the continuous strength graph given. (Shaft material St37)
