4–15. the post is made of douglas fir and has a diameter of 100 mm. if it is subjected to the load of 20 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 f at its bottom needed for equilibrium. also, what is the displacement of the top of the post a with respect to its bottom b? neglect the weight of the post.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
