In an experimental determination of principal stresses a cantilever of hollow circular cross section is subjected to a varying bending moment and torque; the internal and external diameters of the cantilever are 40 and 50 mm, respectively. For a given loading condition the bending moment and torque at a particular section of the cantilever are 100 and 50 Nm, respectively. Calculate the maximum and minimum principal stresses ata point on the outer surface of the cantilever at this section where the direct stress produced by the bending moment is tensile. Determine also the maximum shear stress at the point and the inclination of the principal stresses to the axis of the cantilever. The experimental values of principal stress are estimated from readings obtained from a 45° strain gauge rosette aligned so that one of its three arms is parallel to and another perpendicular to the axis of the cantilever. For the loading condition of zero torque and varying bending moment, comment on the…

1. (a) Explain briefly why a single-cylinder ('mono cylinder') may be replaced with a force-fitted compound cylinder ('duplex cylinder') with the same inner and outer diameters for a high internal pressure bearing application. (b) An alloy steel cylinder of bore radius (n) 40 mm and outer radius (R) 60 mm is subjected to an external pressure of 30 MNM2.

(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).
