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

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
