The post is made of Douglas fir and has a diameter of 100 mm. (Figure 1) It is subjected to the load of 20 kN

and the soil provides a frictional resistance distributed along its length and varies linearly from w=2.9 kN/m at y=0 m to w=8.7 kN at y=2 m

. Neglect the weight of the post.

B) What is the displacement of the top of the post A with respect to its bottom B?
