Problem 1 If an Airy Stress Function is given by (Cos[x] + y) a. What are the stress components zx and zy? b. What are the stress components xx yy, xy? c. If the loading is Plane Stress what is ? c. If the loading is Plane Strain what is z? Problem 2 In class lecture we discussed the stress function in detail. Plecture == C50x5+C41 x y +C32 x y+C23x y +C 14 x y+C05 y +C40 x+ C31x3y+C22x y+C13 x y + C04 y+C30 +C21 x y+C12 x y+C03 y +C20 x+C11 xy+C02 y Using the same values for the constants C40, C31, C22, C11, C13, and C04, the stress function Passignment = C40x+C31 x y +C22 x y+Cxy+C13xy +C04y Solves a very similar problem. Draw the Free Body Diagram including coordinate axes (origin and directions) of the beam loading corresponding to this stress function.
