A steel vessel in the form of a cone is filled with fluid of density 1100 kg/m. The shell supports an external pressure P = 3 kPa. It has a base diameter of 2m and a half-included angle of 30 degrees. Point A is at mid- thickness of the shell, 1.2 m down from the apex. The wall thickness is 4mm. Applying the membrane stress theory, calculate the three principal stresses and the Tresca stress intensity at point A. Principal stresses, from max to min: MPa, MPa, MPa Tresca stress intensity: Mpa Your answers should consist of at least 3 significant figures. Whenever necessary, use g = 9.81 m/s. You must submit your final answer in the text box, and include complete working in your PDF submission. Po 30 2 m A 1.2 m
