A design wave with height $H=1\mathrm{.}0m$ and period

$T=10$ s $($five eights of the way through the wave

cycle, $t=5\frac{T}{8},$ acts on a vertical circular pile

with a parameter $D=0\mathrm{.}25m$ in depth $d=3\mathrm{.}0m.$

Assume that $C_m=1\mathrm{.}8,C_d=0\mathrm{.}6,$ and the density

of seawater $=1025\mathrm{.}0k\frac{g}{m^3}.$

Find: $(1)$The maximum total horizontal force

and $(2)$ the maximum total moment around the

mud line of the pile.
