2. A sign of dimensions 2.0 m x1.2 m is supported by a hollow circular pole having outer diameter 220mm and inner diameter 180 mm (see figure). The sign offset 0.5 m from the centerline of the pole and its lower edge is 6.0m above the ground. 0.5 m A B -2.0 m Bills Bookstore 1.2 m + 6.0 m Determine the principal stresses and maximum shear stresses at points A and B at the base of the pole due to wind load, W of 4.8 KN against the sign. Assume that W acts at the midpoint of the sign. Consider the effects of transverse shear stresses. (30 points) A 180 mm 220 mm B 2.
