QUESTION 3: Three forces act on a pile as shown. If the resultant of the three forces is equal to 500 N and is directed vertically, what is the magnitude and direction of F3. F2= 100 N F3 F,= 75 N 35° 40° Pile (Answer: F3=365 N, E=76.8°)
The wooden pile shown in the figure has a diameter of 100 mm and is subjected to a load of P = 70 kN. Along the length of the pile and around its perimeter, soil supplies a constant frictional resistance of w = 4.99 kN/m. The length of the pile is L = 4.2 m and its elastic modulus is E = 8.7 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.
solve this question please.
A static load test has been conducted on a 60 ft long, 16 in square reinforced concrete pile which has been driven from a barge through 20 ft of water, then 31 ft into the underlying soil. Telltale rods A and B have been embedded at points 30 ft and 59 ft from the top of the pile, respectively. The data recorded at failure was as follows: Load at head = 139,220 lb, settlement at head = 1.211 in, settlement of telltale rod A = 1.166 in, settlement of telltale rod B = 1.141 in. Use the data from telltale rod A to compute the modulus of elasticity of the pile, then use this value and the remaining data to compute q'n and the average fn value. Hint: Telltale rod A is anchored only 1 ft from the mud line (the top of the soil). There is essentially no side friction resistance between the top of the pile and this point, so the force at a depth of 30 ft is essentially the same as that at the top of the pile.
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.

A wood pile driven into the earth supports a load P=400 KN entirely by friction along its sides (see figure). The friction force f per unit length of pile is assumed to be distributed over the surface of the pile. The pile has length L=2m, cross sectional area A=1500 square mm, and modulus of elasticity E=30000 MPa. Include free body diagrams to illustrate derivations. Determine the deformation of the pile.
