Question (5): A sign is supported by a pipe (see figure) having outer diameter 110mm and inner diameter 90mm. The dimensions of the sign are 2.0m1.0m, and its lower edge is 3.0m above the base. Note that the center of gravity of the sign is 1.05m from the axis of the pipe. The wind pressure against the sign is 1.5kPa determine (a) the normal and shearing stresses located at point A (b) the principal planes and principal stresses at point A
