A hydraulic jack $)=(0\mathrm{.}8$ as shown in Figure $K$ have $2$ pistons with diameter $200mm($left$)$ and $400mm($right$).$ There is a colume in between used to measure pressure inside the system, $3736N$ was applied at the smalier piston. Determine the force that mugs be applied on the bigger piston to maintain ats postion in $N$
