Atitanium tube 200mm diameter and 5mm wall thickness is subjected to an internal pressure of 13.5mpa. the tube contains a longitudinal crack along its full length. assuming that the tube can be approximated by a single edge notched plate subjected to a tensile stress equal to the hoop stress in the tube determine the crack length to cause failure. you may assume that the material fracture toughness is 55 mpavm. provide your answer in mm enter answer
