B An Alloy Steel Cylinder Of Bore Radius M 40 Mm And Outer Radius R 60 Mm Is Subjected To An External Pressure Of 1 (71.05 KiB) Viewed 24 times

(b) An alloy steel cylinder of bore radius (m) 40 mm and outer radius (R) 60 mm is subjected to an external pressure of 30 MNm? (1) Determine the circumferential stresses generated at the bore and outer surface of the cylinder. (II) Sketch the form of distribution of radial and circumferential stresses across a radius. (c) The cylinder in (b) above is to be used as a hydraulic cylinder. For this application, it needs to be strengthened by shrink fitting onto it a sleeve of outer radius (ro) of 80 mm of the same steel as shown in Figure 1(c). The interference pressure generated due to this fit is 30 MNm2 Observe: This pressure is the same as the external pressure used in the calculations in part (b). (1) Determine the circumferential stress generated in the sleeve (outer cylinder) at the common interface due to this fit. (II) Sketch the form of distribution of radial and circumferential stresses across a radius in the compound cylinder. Assembly Figure 1(c) (d) If Young's modulus for steel is 210 GNm? calculate the shrinkage Allowance (Oc) required to generate the fit in (c).
