What is a trebuchet? a trebuchet is a medieval siege-engineIt was used to attack castles in the middle ages It could hurl heavy objects a huge distance!
How to attack castles The Romans used siege-engines in battle -The ballista was like a huge crossbow which shot large bolts at the enemy. It was good for killing people inside wooden buildings!
the catapult This was also used by the RomansIt used tension to power the throwing arm and hurl stones, fire and even diseased bodies at the enemy!
The medieval period Between 1000 ad and 1500 ad was the age of the castle At first, they were made of wood and earth.
Castles get stronger Stone keep castles were built for better protection
Concentric castles These were the most difficult castles to attackThey had several walls around them Caerphilly castle
Siege-engines A siege is when a castle is surrounded by an enemyThey can wait until the defenders starve…. ….or hasten the victory by attacking the castle with siege-engines….
Basic siege-engines The battering-ram would try And bash in the gateThe bolt-shooter was like the roman ballista
Basic siege-engines 2 The onager used the tension of a twisted rope to hurl stones over the castle walls The stone-thrower was a bigger version of the onager
Basic siege-engines 3 The tower allowed attackers to get into the castle over the walls But in the twelfth century, the French developed a terrifying new weapon….
The trebuchet The trebuchet could hurl stones weighing up to 200 kgThis was over six times more powerful than the best catapults It used a weighted sling to hurl objects…
How it works The trebuchet is based on the sling motionA large weight pulls down the arm This levers up the long end, whipping the sling in a circular motion
Building a trebuchet You will build a micro-treb using the materials given… Micro-treb stands 4 inches tall, with a 7 inch throwing arm.
The weight-bucket Micro-Treb's weight bucket is framed in wood with paper siding. It is then filled with tiny pebbles.
The fulcrum The fulcrum is what the arm swivels round onUse a bent-over paper clip
The base A small bit of card-paper forms the base of the machine, providing the skit for the finishing nail to slide on. (The nail is poked through the card stock in this shot to hold position.)
The challenge How will you get your micro-treb to work?You’ll need to design it well Think about the length of the wood and the sling Make sure the construction is strong!
Basic design help
A good design
