The axially aligned pressure vessel, shown in Fig Q2, is made from aluminium exhibiting a Young's Modulus of 73GPA and a Poisson ratio of 0.34. It has an outer diameter D, of 86mm and a wall thickness t of 5mm. The vessel is subject to an internal pressure P of 150bar and externally applied torque T of 4.5kNm. a) Draw the 2D planar state of stress of any finite element located on the outer surface of the pressure vessel, according to the polar coordinate system provided. b) Sketch the longitudinal, circumferential and planar shear strain profile through the thickness of the vessel wall. c) Determine the minimum factor of safety for the given load cases, assuming the aluminium has a yield strength of 175MPA, and comment on the most likely mode and locus of failure.

Calcuate Torsion From Point A to Point C and Bending from Point A to Point B and from Point A to Point C. Draw a FBD from point A to point B and another for point A to C indicating what stresses are been calculate. Use the stress tensor and stress cube to Indicate what forces are acting at point A. Force apply at point B is 70lb Distacen from Point A to B is 12 in or 1 feet long Distacen from Point A to C is 3 in Handle diameter 0.625 in
