c. A concrete pile is 15m long and has 406 mm diameter circular cross section. The pile is fully embedded in sand, for which the unit weight y =18 kN/m³ and the frictional angle o = 30°. i. Calculate the ultimate point load Qp. ii. Determine the total frictional resistance Qs. iii. Determine the total ultimate load of the pile.

Please round to the nearest Hundredth (i.e., 0.01). No Comma! A square pile is driven into a homogeneous sand layer. The pile's width (diameter) is 0.5m. The standard penetration resistance near the vicinity of the pile is 21. Calculate the ultimate point force (Qp) of the pile. Use Briaud & Tucker method. Hint: Qp = qp x Ap Qp = kN

A 40 cm diameter concrete pile, is driven to a depth of 15 m in a deep deposit of clay having unconfined compressive strength of 80 kN/m². The design load carrying capacity of pile will be [Assume α = 0.8 and FOS = 3] - (a) 648.42 kN (c) 432.28 KN ;) (b) 216.14 kN (d) 1296.84 kN

63.A timber pile of length 8m and diameter of 0.2m is driven with a 20 kN drop hammer, falling freely from a height of 1.5m. The total penetration of the pile in the last 5 blows is 40 mm. Use the engineering news record expression. Assume a factor of safety of 6 and empirical factor (allowing reducing in the theoretical set, due to energy losses) of 2.5 cm. The safe load carrying capacity of the pile
