A uniform metal plate shaped like a triangle $A B C$ has a mass of $540 \,g$. The length of the sides $A B, B C$ and $C A$ are $3 \,cm , 5 \,cm$ and $4 \,cm$, respectively. The plate is pivoted freely about the point $A$. What mass must be added to a vertex, so that the plate can hang with the long edge horizontal?
