A steel H$-$pile $($section HP $330$ X $149)$ is driven by a hammer. The maximum rated hammer energy is $54\mathrm{.}23$kN$$m$,$ the weight of the ram is $53\mathrm{.}4$kN$,$ and the length of the pile is $27\mathrm{.}44$m$.$ Also, we have coefficient of Restitution $=0\mathrm{.}35,$ weight of the pile cap $=10\mathrm{.}7$kN$,$ hammer efficiency $=0\mathrm{.}85,$ number of blows for the $2\mathrm{.}54$cm of penetration$=10,$ and Ep $=207$x$10$kN$/$m$^2.$

Estimate the pile capacity using the modified EN formula. Use FS $=3$
