Question

PROBLEM 2 The gage gas pressure of the in tank is X.X MPa. (where XX are the first two digits of your student number), an the force F=XKN, (where X is the first digit of your students number). The pressure vessel AB has an inner diameter of 500 mm and a uniform wall thickness of 8 mm. Determine: A. The State of stress at position b. B. Draw an element of material and show the state of stress at the normal x-y coordinate system. C. Determine the principal stress using the Mohr Circle, provide evidence of all your work. 7-som 750mm D F 500 mm
