Fig. P$3\mathrm{.}49$ and P$3\mathrm{.}50$

$3\mathrm{.}50$ When a force F is applied to the handle of the valve shown, its moments about the $x$ and $z$ axes are $M_x=-77lb*ft$ and $M_z=-81lb.$ft$,$ respectively. For $d=27in.,$ determine the moment $M_y$ of F about the $y$ axis.

Could you please do $3\mathrm{.}50!!!$
