What would be the load carrying capacity of a 250 mm-diameter and 15 m-long timber pile driven into soft clay with an unconfined compressive strength of 40 Kpa? What percentage of the total load is carried by the shaft? use a safety factor of 2.5 .for problem 7 you are not given enough information to do an effective stress analysis (i.e. what is the friction angle, where is the water table located?), so only do a total stress analysis for the problem.
