(9) A 3161 steel tube is used to contain 6MPa pressure. The tube has a "Y' where one branch goes to an air motor and the other end to a pressure gauge. (see Figure below) a) 3/4" OD 1" OD EEEEEEEE Strain gauge b) c) Z-axis -Z-axis The entire pipe is made out of the same material with the same wall thickness to make fabrication easier. What is the minimum wall thickness required to hold the pressure (3161YS=280MPa). Consider van Mieses stress and safety factor=2) (9) The pipe is monitored with a strain gauge (a tool to measure the deformation) in the pipes circumferential direction. The strain gauge shows an extension of 0.02mm at a circumferential distance of 20mm (see red box in the sketch arrow indicates the direction of the strain). What is the associated pressure in the pipe and is this a reason for concern? b) (9) The two tubes are attached to each other via a weld. Let's only consider the stress in Z1 axis caused by the pressure. The welded area is a notch, and one may consider the fracture toughness of 3161 is 40MPa.m.5. What is the maximum notch size we can tolerate (see cartoon above) (9) A 3161 steel tube is used to contain 6MPa pressure.
