Please help me solve Determine the length, L, of a driven timber pile required to support the load shown in Figure P13.4. The diameter of the pile is 450 mm. A factor of safety of 2 is required. Assume the pile–soil interface friction is equal to the critical state friction angle.
7. If a 45 cm diameter pipe pile is driven into clayey soil to a depth of 12 m. (a) what would the allowable load capacity (Q) be? The water table is 2 m below the ground surface and the soil profile consists of two clay layers (refer to the figure below). Use the ß method to calculate skin friction and the R=30° for all clay layers.

The wooden pile shown in the figure has a diameter of 95 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 = 4.82 kN/m. The length of the pile is L = 4.0 m and its elastic modulus is E = 10.4 GPa. Calculate (a) the force FB needed at the base of the pile for equilibrium. (b) the magnitude of the downward displacement at A relative to B.
Please answer 11.7
The pile P has a mass of 800 kg and is being driven into loose sand using the 300-kg hammer C which is dropped a distance of 0.5 m from the top of the pile. Determine the initial speed (in m/s) of the pile just after it is struck by the hammer. The coefficient of restitution between the hammer and the pile is e = 0.1. Neglect the impulses due to the weights of the pile and hammer and the impulse due to the sand during the impact.
