Show that Airy's stress function D = Cre sine satisfies the biharmonic equation. Also determine the stresses in polar co-ordinate system. 2 A 10-in. length of steel tubing (with properties of E 30 X 106 psi, v = 0.3 and a 7X10-5 F) having a cross-sectional area of 1 square in is installed with fixed ends so that it is stress- free at 80°F measurements indicate that the fixed ends separate by 0.008 in. What loads are exerted on the ends of the tube, what are the resultant stresses and strains? 3 Careful In operation, the tube is heated throughout to a uniform 480°F.
