Secrets of Lost Empires: Destroy the Castle

5/20/2014 3:00:00 PM
NOVA Online, as part of a section of the Medieval Siege, has a game to pit your understanding of force and motion against the walls of the castle. For your use is a trebuchet, a wall-crushing machine, but only if it is adjusted correctly. Before you begin your siege, read about how the trebuchet works.  You’ll need to take into consideration the distance to the castle, the type of launch pad you want to use, the sling length, ball weight, and the kind of counterweight.
