A hollow circular pole, 3 m high, has an outside diameter of 300 mm and a thickness of 6 mm. It is subjected to the following loads: 1. A vertical compressive load, P = 3 kN at an eccentricity of 100 mm from the centroid of the section. 2. A lateral load, H = 0.45 kN at the top of the pole. The weight of the pole is 150 N/m. Which of the following gives the maximum compressive stress (MPa) at the base of the pole due to the vertical loads?
