Problem $5\mathrm{.}1($a$)$ and $5\mathrm{.}1($c$)$

For the following cases, determine the allowable gross vertical load$-$bearing capacity of the

foundation. Use Terzaghi's equation and assume general shear failure in soil. Use FS $=4.$

Problem $5\mathrm{.}3($a$)$ and $5\mathrm{.}3($c$)$

Use the general bearing capacity equation $[$Eq$.(5\mathrm{.}30)]$ to solve the following:

a$.$ Problem $5\mathrm{.}1$a

b$.$ Problem $5\mathrm{.}1$ c

Can someone help me with problem $5\mathrm{.}3$ A$.$
