and that the formulas for (u, v) given in are thus equivalent.

.
An infinite plane strip is bounded by the lines
y
= ±1. The stresses on the lines
y
= ±1

are
σy
= cos
x, τxy
= 0. There is no body force. By assuming an Airy stress function

of the form
f (y)
cos
x, determine
σx, σy, τxy
as functions of (x, y).
