Item 1 Learning Goal: Learning how to use stress intensity factor for Mechanical Engineering Design. A plate of width of 1.4 m and length 2.8 m is required to support a tensile force in the 2.8-m direction of 4000 kN. Inspection procedure will detect only though-thickness edge cracks larger than 2.7 mm. The two Ti-6AL-4V alloys in Table 5-1 will are being considered for this application, for which the safety factor must be 1.3 and minimum weight is important. Which alloy should be used? Part A Find the minimum required thickness to resist yielding for two Ti-6AL-4V alloys. Express your anwser in mm. Round your anwser to 3 significant digits. Result for the weaker alloy first, then the stronger alloy Submit My Answers Give Up

Solution

minimum thickness = 12.05
