The diagram illustrates a crane holding up a load $L$. A mass is used to supply a balancing load $W$. The load is positioned so that the system is in exact equilibrium, with $Wx = Ly$. The ground exerts a reaction force $R$. The distance $x$ remains unchanged. If the load is shifted further outward so that the distance $y$ increases, and the crane still does not topple, which statement is correct?
