A cylindrical pressure vessel is made by shrinking a brass shell over a mild steel shell. Both cylinders have a wall thickness of 6 mm. The nominal diameter of the vessel is 750 mm and is to be used in all calculations involving the diameter. When the brass cylinder is heated 50°C above room temperature, it exactly fits over the steel cylinder which is at room temperature. What is the stress in the brass cylinder when the composite vessels cool to room temperature? E for steel=200 GPA E for brass = 100 GPA a for steel = 12 x 10"/C a for brass = 19 x 106/°C Wrong answers will be downvoted
A pipe carrying steam at 3.5 MPa has an outside diameter of 450 mm and a wall thickness of 10 mm. A gasket is inserted between the flange at one end of the pipe and a flat plate used to cap the end. How many 47-mm-diameter bolts must be used to hold the cap on if the allowable stress in the bolts is 80 MPa, of which 55 MPa is the initial stress?
14. A solid steel shaft of 0.2 m diameter has a bronze bush of 0.3 m outer diameter shrunk on to it. In order to remove the bush, the whole assembly is raised in temperature uniformly. After a rise of 100°C the bush can just be moved along the shaft. Neglecting any effect of temperature in the axial direction, calculate the original interface pressure between the bush and the shaft. For steel: E = 208 GN/m², v= 0.29, a = 12 x 10-6 per a = 18 × 10 6 per For bronze: E= 112 GN/m², v=0.33,
Consider the steel pressure vessel shown in Figure 1, intended to withstand an internalpressure of 40 MPa. The vessel has an outer diameter of 300 mm, an overall length of 500mm and a wall thickness of 30 mm. There is a 30 mm fillet radius where the interior wallsurface joins the end caps, as shown in the section view in Figure 1. The vessel is made ofASTM A27 steel. Use ANSYS Workbench to simulate this component and comment on itssuitability for production given the loading conditions detailed above.
A pipe carrying steam at 3.5 MPa has an outside diameter of 450 mm and a wall thickness of 10 mm. A gasket is inserted between the flange at one end of the pipe and a flat plate used to cap the end. How many 40-mm-diameter bolts must be used to hold the cap on if the allowable stress in the bolts is 105 MPa, of which 55 MPa is the initial stress? What circumferential stress is developed in the pipe? Why is it necessary to tighten the bolt initially, and what will happen if the steam pressure should cause the stress in the bolts to be twice the value of the initial stress? *

3. During the design of spherical pressure vessel for space programs, a primary criterion is the mass of the vessel (which determines how much it costs to put it into the orbit). Given the stress in a thin walled spherical vessel is tensile and given by: Pr 2t where P is the pressure in the vessel, r is the radius and t is the wall thickness. For safety, materials will experience stress smaller that yield stress by a safety factor N. 10-1 Show that the minimum mass of the pressure vessel will be m= 2Νπ Pr' where p is the density of material. ys Given the data in Appendix B1 and B4 in the textbook, select the material (from following table) that will result in the lightest possible pressure vessel.

shows two tubes, one of copper and another of steel of equal length and rigidly connected at their ends so that under all conditions they are of equal length. The copper tube has internal and external diameters of 100 mm and 125 mm respectively whilst the internal and external diameters of the steel tube are 75 mm and 100 mm respectively. If the original length of the tubes was 375 mm, for a temperature rise of 22o C calculate: 1 The stress set up in each tube; 2 The final length of the tubes. Assume: α copper = 18,7 x 10-6/ 0 C; E copper = 82 GPa α steel = 12,6 x 10-6/ 0 C; E steel = 207 GPa
