Show that the following function may be used as an Airy stress function
+ = Ar + Br²y + Cxy
Evaluate A, B and C for the rectangle shown in Figure Q3:
(1) there are no external loads for any kind applied along KN;
(2) along KL there is a uniform normal load p;
(3) and along MN there is no normal load;
(4) along KL, LM and MN there are shear stresses (but none along KN).
Make a neat sketch of the stresses along the boundary KLMN.
