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 ydirection normal to the weld) is 60 MPa. Determine the internal pressure using Mohr’s circle. Also determine the axial and hoop
strains. (Hint: First determine the axial and hoop stresses.) 41:
