This siege weapon was used in Medieval Times. It was used to hurl
rocks against castle walls. The counterbalance weight on the end
of the main arm would be many tons in weight and close to the pivot
point. A short, slow movement by the counterbalance weight uses the
leverage of the long arm to create a long, fast movement at the other
end of the arm. The sling shot at the end provides further magnification
of the speed. The result is a ball, as much as 300lbs in weight being
flung at over 100mph with huge destructive force.
When a castle was under siege dead animals were sometimes flung into the castle
to spread disease.
