What are the differences between thin-walled and thick-walled cylinder in terms of   

What are the differences between thin-walled and thick-walled cylinder in terms of dimension and variation of stresses [1 mark] WITHOUT PERFORMING ANY CALCULATION sketch the yield loci of the state of plane stress according to Rankine, Tresca and Von-Mises failure theories, indicating the stress limit in the sketch [3 marks] b) A closed-ended thick cylinder has an external diameter of 400 mm and is required to maintain pressurized oil at a pressure of 10 MPa. If the yield strength of the cylinder material and the design factor of safety are 220 MPa and 2.5, respectively, determine the minimum thickness, t of cylinder that can be used according to the following failure criteria: i) Maximum shear stress theory (Tresca) ii) Maximum normal stress theory (Rankine) If the cylinder is to be fabricated, which thickness is to be chosen? Give reasons to your answer.
