Prob#1. A circular foundation is constructed over sand stone rock. The diameter of the foundation is 3m. The depth of the foundation is 1.5m and the unit weight of soil above the base of the foundation is 17.5 kN/m. For the sand stone rock , y = 25 kN/ m', c= 60 KN/m?, = 32 and the ROD = 0.4 . Calculate the maximum allowable load for the foundation. Use FS =4. The 28 day strength of concrete is 35 MN/m?.Table 3 Variation of If with Df / B, B/ L, and us B/L DJ / B 0.2 0.5 1.0 0.3 0.2 0.95 0.93 0.90 0.4 0.90 0.86 0.81 0.6 0.85 0.80 0.74 1.0 0.78 0.71 0.65 0.4 0.2 0.97 0.96 0.93 0.4 0.93 0.89 0.85 0.6 0.89 0.84 0.78 1.0 0.82 0.75 0.69 0.5 0.2 0.99 0.98 0.96 0.4 0.95 0.93 0.89 0.6 0.92 0.87 0.82 1.0 0.85 0.79 0.72 Assume that the foundation is rigid and determine the elastic settlement the foundation would undergo.

Se mmQUESTION 11 Pearson's second skewness coefficient is defined as (3 * [u - median)/o). You are examining financial statistics for the rate of return of a financial product your company sells and find out that the standard deviation is 0.5 and the Pearson coefficient of skewness is 1.5. Suppose that by the end of this year, you receive the updated statistics and find out that the mean increased by 0.2 and the median and standard deviation stayed unchanged. What would be the updated value of Pearson's second skewness coefficient? 0 0.4 0 1.2 O 25 Q 2.6 O2.7
