1.	A vertical retaining wall of 5m height has to support soil having unit weight of 18KN/m3, effective cohesion of 12KN/m2, and effective friction angle of 30∘, As per Rankine's earth pressure theory and assuming that a tension crack has occured, the lateral active thrust on the wall per meter length (in KN/m, round off to two decimal places), is 21.71
Answer» A vertical retaining wall of 5m height has to support soil having unit weight of $18 K N / m^{3}$ , effective cohesion of $12 K N / m^{2}$ , and effective friction angle of $30^{\circ}$ , As per Rankine's earth pressure theory and assuming that a tension crack has occured, the lateral active thrust on the wall per meter length (in KN/m, round off to two decimal places), is 21.71

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 40mm. 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 (in kN, round off to 2 decimal places) is151.515
