The wooden pile shown in the figure has a diameter of 120 mm and is subjected to a load of P = 80 kN. Along the length of the pile and around its perimeter, soil supplies a constant frictional resistance of w = 4.69 kN/m. The length of the pile is L = 4.9 m and its elastic modulus is E = 11.6 GPa. Calculate (a) the force Fg needed at the base of the pile for equilibrium. (b) the magnitude of the downward displacement at A relative to B.
