Question
![A steel post (E= 30x10° psi) having thickness h =- in. and height l = 74 in. supports a stop sign (see the figure: s = 11.5 in.). The height of the post L is measured from the base to the centroid of the sign. The stop sign is subjected to wind pressure p = 15 lb/ ft normal to its surface. Assume that the post is fixed at its
base.
