5. (5) Consider the thin-walled pressure vessel below with internal gage pressure p, mean diameter d, and thickness t. CI. d X a. Determine (in terms of p, d, and t) the stresses on the x y element and draw this element b. Determine principal stresses and draw this element c. Determine the in plane maximum shear stress and draw this element d. For a thin walled vessel, the radial stress ( at our point) is 0. Draw all 3 Mohr's Circles, identify the three principal stresses, and determine the absolute maximum shear stress e. Identify the plane on which this occurs. (Hint, consider drawing a cross section of the vessel)
