(a) For a thin cylindrical, closed pressure vessel, containing fluids with pressures p; internally and poexternally, (i) derive the expressions for ơee and ơzz at any radius r and state the values for ơrr at r and r (ii) the case when po > p, where p 0 (gage units) conditions stated in (a). -ro. (b) Simplify the above expressions for (i) the case when p > po, where po 0 (gage units) and (c) Symbolically, obtain the expression for...
Problem 3 [35 marks] An inspection of a failed thin walled pressure vessel (cylinder with closed ends) shows through- the-thickness cracks in the axial (or longitudinal) direction. The length of the cracks varies from 10 mm to 25 mm. The pressure vessel has radius R = 1.5 m, wall thickness t = 30 mm, and was manufactured from aluminium with fracture toughness properties Kịc = 50 MPa m12. a) Determine the pressure at which the vessel is expected to have...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
