Thirty-six piles, 0.6 m in diameter, are spread at 2.4 m centres in a 6 x 6 group. The piles extend between depths of 3 m and 18 m in a layer of stiff clay 28 m thick, overlying rock. The undrained shear strength of the clay at a depth of 18 m is 145 KN/m2 and the average value over the pile length is 105 KN/m2. The following parameters have also been determined for the clay: α = 0.4, A = 0.28, Eu = 65 MN/m2 and mv = 0.08 m2/MN. If the pile group carries a load of 21 MN, determine the load factor and the total settlement.

V = X'(t) = -t^2 + 6 m/s Implies X(t) = -(1/3)*t^3 + 6*t The initial position is zero in this case. This function will initially increase (this means the object is moving forward), then the negative force will be too strong, so the object will start moving backwards. calculate the maxima and minima. Graph the function X(t). Describe the motion. Every detail.
