2. (50 pts) A Mechanically Stabilized Earth (MSE) wall is to be constructed as shown in the figure below. Answer the following questions regarding this wall. a) (5 pts) What

is the Rankine active earth pressure coefficient that should be used? b) (15 pts) What is the magnitude, direction, and height of the lateral pressure resultant(Fa)? What are the magnitudes of the horizontal and vertical components of the lateral pressure resultant? c) (10 pts) What is the total overturning moment if the reference point is placed at thetoe of the wall? d) (10 pts) What is the total resisting moment if the reference point is placed at the toeof the wall? (5 pts) Does the wall meet the minimum factor of safety for overturning (2.0)? f) (5 pts) Does the wall meet the minimum factor of safety for sliding (1.5)?
