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.

A steel panel is subjected to a compressive loading in order to improve the panel stiffness and to increase its buckling strength. It is swaged with the swage depth of 13 mm and swage angle of 60.07°. Its profile is as shown in Fig.Q2. Typical dimensions are shown in the figure and the thickness of the panel is 0.8 mm. The effective length of the panel is 750 mm. The relevant properties are: Modulus of elasticity Yield stress 200 GN/m? 240 MN/m? . Assuming that the buckling stress coefficient for a panel simply supported on both sides is 3.62 and that the post buckling relationship for the panel is Oy = 0.40, +0.60, where oav = average panel stress, o, = edge stress in panel and o = panel buckling stress, determine (a) the load/swage pitch at which initial buckling of the panel will ccur, (b) the instability load per swage pitch.

A workshop crane is lifting a load of 28 kN through a wire rope and a hook. The weight of the hook etc is 15 kN. The rope drum diameter may be taken as 30 times the diameter of the rope. The load is to be lifted with an acceleration of 1.2 m/sec2. Take a factor of safety of 6 and Young's modulus for the wire rope is 80 kN/mm2. The ultimate stress may be taken as 1800 MPa. The cross-sectional area of the rope may be taken as 0.38 times the square of the wire rope diameter. Neglect the effect of impact load. Calculate the diameter of the wire rope.
