History
The traction trebuchet is believed to be an ancient war engine which was invented in China in 300BC. It is thought that the trebuchet may have developed from the stave sling. In the traction trebuchet a large troop of men pulled down on ropes to propel the missile. The trebuchet reached Europe during the Medieval era in 500 AD and was used extensively by the French and the troop of men were replaced with a large fixed, or pivoting, counterbalance weight. The Trebuchet (Trebuchet) was introduced in England in 1216 during the Siege of Dover - as were many other types of siege engine. Louis the Dauphin of France crossed the Channel with a large force and laid siege to Dover Castle making a violent and incessant attack on the walls. He used the trebuchet against the walls of Dover Castle. The constable of Dover castle was Hugh de Burgh - he refused to surrender.
Proposed Problem and Design Specifications The most important criteria for our design are the following:
Can be constructed in the fabrication shop
Budget must be under $50
Maximum size can be 2 x 2 foot base, 3 feet height The class has to be able to use the resources available. If the product cannot be built in the
