1) You were hired to analyze some stability parameters of a retaining wall, specifically safety against tipping and penetration. This retaining wall was produced in concrete and its specific weight corresponds to Yc= 23.0 kN/m³. 
According to the soil profile obtained in the characterization tests, it is a sandy and non-cohesive soil (C=0kPa), with an internal angle φ=25º and Ysolo= 15.Y kN/m³, which results in buoyancy active in the retaining wall structure. At the proven depth, no groundwater level was found. The geometric characteristics of the retaining wall are shown in the image:
 
Given the information provided, a safety check regarding tipping and wall penetration is requested.

Consider:
⁃ X, Y and Z involve the penultimate. penultimate and last digit of the student's RA, respectively. In this case, it is X=6 Y=1 Z=0. 
- The safety factors to be considered for tipping and penetration are, respectively, FStomb=1.5 and FSdesliz=1.5;
- There is no overload on the soil profile;
- Neglect vertical friction between the surface of the retaining wall and the ground;
- Neglect soil-wall adhesion at the base of the structure;
⁃ The shear force at the base of the wall is given by the formula: S=Wtotal.tg φ, where Wtotal is the total weight of the wall.

RA = 4633610
