cantilever retaining wall For the cantilever retaining wall shown in the figure below, the wall dimensions are \( H=14 \mathrm{ft}, x_{1}=1 \mathrm{ft} ., x_{2}=2 \mathrm{ft}, x_{3}=3 \mathrm{ft}, x_{4}=4 \mathrm{ft} ., x_{5}=1.5 \mathrm{ft} ., D=2.5 \mathrm{ft} \) and \( \alpha=15^{\circ} \). The soil properties are as follows: \( \gamma_{1}=108.4 \# / \mathrm{ft}^{3}, \varphi_{1}^{\prime}=28^{\circ}, \gamma_{2}= \) \( 116.8 \# / \mathrm{ft}^{3}, \varphi_{2}^{\prime}=36^{\circ} \), and \( c_{2}=406 \# / \mathrm{ft}^{2} \). This data and figure applies to the Determine the Factor of Safety due to sliding. Do not include the Passive Earth Pressure in this analysis. 1 point Determine the Factor of Safety due to due to bearing capacity failure. The ultimate bearing capacity for the \( 50 i l, q_{u}=4,106 \# \mathrm{ft}^{2} \)
