Right Answer is: B
SOLUTION
For no tension failure
\({B_{min}} = \frac{H}{{\sqrt {G - K} }}\)
\({B_{critical}} = \frac{H}{{\sqrt G }}\;\left( {K = 0} \right)\)
For no overturning
\({B_{min}} = \frac{H}{{\sqrt {2\left( {G - K} \right)} }}\)
\({B_{critical}} = \frac{H}{{\sqrt {2G} }}\;\left( {K = 0} \right)\)
For no sliding failure
\({B_{min}} = \frac{H}{{\mu \left( {G - K} \right)}}\)
\({B_{min}} = \frac{H}{{\mu G}}\;\left( {K = 0} \right)\)
