_______________________________________________________________________ PROBLEM (8.90) A closed cylindrical tank fabricated of 10-mm-thick plate is subjected to an internal pressure of p = 6 MPa. Determine: (a) The maximum diameter if the maximum shear stress is limited to 30 MPa. (b) The limiting value of tensile stress, for the diameter found in part (a).
