Q.3// A thin-wall tube with closed ends is subjected to a maximum internal pressure of 35 MPa in service. The mean radius of the tube is 30 cm. (a) If the tensile yield strength (hoop direction) is 700 MPa, what minimum thickness must be specified to prevent yielding? (b) If the material has a yield strength in shear of k 280 MPa, what minimum thickness must be specified to prevent yielding? (c) For (a) only, use von Mises criteria to determine the necessary yield strength to prevent yielding.
