mass and balance

m=m.d

%mac=(le mac to cg/mac).100

shifting mass     

m/M=d/D                 m->mass of the load being shifted

                                M->a/c mass

                                d->distance of the CG is being shifted

                                D->distance of the mass is shifted

ADDING OR REMOVING LOAD

m/Mnew=d/Darm to CGO        m/Mold=d/Darm to CGN
