Unformatted text preview: Name: SDWTWI‘J Session: The pressurized tank (E, V) with diameter of 1000 nun is made of 8 mm thick plate. The normal stress cry (stress in the y-direction normal to the weld) is 60 MPa. Determine the internal pressure using Mohr’s circle. Also determine the axial and hoop strains.
