An electric power transmission pole is 12 m above ground level and embedded 2 m into the ground. The butt diameter is 450 mm and the tip diameter (the top of the pole) is 320 mm. The weight of the pole, cross arms, and wires is 33 kN. Assuming the pole transmits the load as a point load, find the change in vertical stress in kPa at 1 m depth. a.17.8 b.63.0 c.393.9 d.3.9
