9-22. The post is made of Douglas fir and has a diameter of 100 mm. If it is subjected to the load of 200 kN and the soil provides a frictional resistance that is distributed along its length and varies linearly from w- 4 kN/m at y-0 to w=12 kN/m at y = 2 m, determine the force Fat its bottom needed for equilibrium. Also, what is the displacement of the top of the post A with respect to its bottom 8? Neglect the weight of the post. 20 KN -12 AN
