A compound vessel is obtained by shrinking an external cylinder of internal diameter equal to 200 mm and external diameter equal to 300 mm over a cylinder of internal diameter equal to 150 mm and external nominal diameter equal to 200 mm. Both cylinders are made of steel (E 205 Gpa) and an interference equal to 0.15 mm is used at the mating surface Calculate the radial and circumferential stresses at the inner and outer surfaces of the two cylinders,...

19 A brass sleeve having an outside diameter of 40 mm is screwed on to a steel stud such that the mean interface diameter is 24 mm. The ends of the assembly are then machined so that the two materials are the same length. If the temperature of the assembly is increased by 60°C and the assembly is then subjected to a compressive force of 40 kN, calculate the magnitude and sense of the stresses...

P.1.9. A bar of mild steel has a diameter of 75 mm and is placed inside a hollow aluminum cylinder of internal diameter 75 mm and external diameter 100 mm; both bar and cylinder are the same length. The resulting composite bar is subjected to an axial compressive load of 1000 KN. If the bar and cylinder contract by the same amount, calculate the stress in each. The temperature of the compressed composite bar is then reduced by 150°C but...

Question Four (a) A steel ring of 300 mm and 200 mm external and internal diameters res solid steel shaft. The interference is arranged such that the radial pressure between the mating surfaces will not fall below 30 MN/m2 whilst the assembly rotates in service. If the maximum circumferential stress on the inner surface of the ring is limited to 240MN/m2, and there is no relative slip between the shaft and the ring, determine...

Question A-36 steel pipe with an outer diameter of 100 mm and an inner diameter of 80 mm subjected to loadings shown in Figure 1. The pipe is rigidly fixed at B and P - 150 kN. Given the yield stress, Oy -250 MPa and factor of safety, F.S. - 1.5 is used against yielding on this entire pipe. (a) For the stress state at the surface, construct the Mohr circle and determine: (1) the total stresses at surface of...

answer 18.11 and 18.12
18.11 A steel ring with an outside diameter of 150 mm and an inside diameter of 100 mm is shrunk onto another steel ring with an inside diameter of 50 mm. An axial force of 56,54 kN is needed to push the rings apart. Calculate the pressure at the mating surface and the shrinkage allowance given that both rings are 20 mm thick and the coefficient of friction between the mating surfaces is 0,2. Using...
