A segment of a generator shaft is subjected to a torque T and an axial force P, as shown in the Figure Q3. The shaft is hollow (outer diameter d2 = 307 mm and inner diameter d1 = 250 mm) and delivers 1800 kW at 4.0 Hz (a) If the compressive force P = 540 kN, determine the stresses produced and the state of plane stress on its surface. (b) Calculate the principal stresses and the maximum in-plane shear stress in the shaft. Specify the orientation of the element in each case.

Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.
