How fast can a trebuchet shoot?
speed of 70 / . The projectile can be assumed to be launched from ground level.
Who built a massive trebuchet?
Trebuchets were known to hurl stones weighing 200 pounds up to 300 yards. King Edward I built the largest known trebuchet, called Warwolf, to assault Stirling Castle in Scotland after a long siege in 1304. When the inhabitants saw what was being built, they tried to surrender based on the sight of it alone.
How were trebuchets built?
he trebuchet was a wooden siege engine designed to destroy castle walls by throwing large rocks at them. The engine was constructed using a sturdy base, a long throwing arm and a bucket to hold weights.
What is the best trebuchet design?
The optimal trebuchet design is one that launches the payload the farthest horizontal distance. This makes sense intuitively since range is a key factor when staging an attack on an enemy.
What is the best ratio for a trebuchet?
General advice is that the optimal ratio is 133:1. A golf ball projectile (1.62 oz) should fire best with 13.46 lbs of counterweight – and a 14 lb bowling ball should have 1862 lbs pulling on the other side of the arm to reach maximum distance.
How do you make a perfect trebuchet?
Step 1: Cut lumber. Using the cutting guide shown, cut the two-by-threes, two-by-two, and one-by-three to length. Step 2: Mark frame. Step 3: Drill holes for pivot arm. Step 4: Assemble trebuchet sides. Step 5: Drill holes for axles. Step 6: Join trebuchet sides. Step 7: Attach braces. Step 8: Mount wheels.
What makes a catapult a catapult?
A catapult uses the sudden release of stored potential energy to propel its payload. Most convert tension or torsion energy that was more slowly and manually built up within the device before release, via springs, bows, twisted rope, elastic, or any of numerous other materials and mechanisms.
When were trebuchets invented?
The trebuchet was invented in France and was first reported to be used in 1124AD in the siege of Tyre (in present-day Lebanon) during the Crusades. As it was much more powerful than a catapult, a trebuchet became the siege weapon of choice.
How do you make a catapult?
Simple craft stick catapult: Stack five craft sticks together and wrap a rubber band around each end. Stack two craft sticks and wrap a rubber band around only one end. Slide the five sticks in-between the two sticks, as shown. Wrap a rubber band where the two sections meet to hold the catapult together.
Is a trebuchet better than a catapult?
Roughly speaking, a trebuchet has a few advantages over a catapult. First, it can handle heavier projectiles. A catapult’s maximum weight tops out at about 180 pounds; trebuchets top out at about 350. Lastly, for a given weight of stone, the trebuchet has a longer range.
Did trebuchets use fire?
‘ The traction trebuchet offered an impressive rate of fire: A 1991 experiment conducted on a model made to ancient standards at the University of Toronto showed that a well-coordinated trebuchet crew could fire four rounds per minute. Yet the traction trebuchet was not without its shortcomings.
How far can trebuchets throw?
Based on historical designs, it stands 18 metres (59 ft) tall and throws missiles typically 36 kg (80 lbs) up to 300 metres (980 ft).
Was the Warwolf real?
The Warwolf, or War Wolf or Ludgar (French: Loup de Guerre), is believed to be the largest trebuchet ever made. It was created in Scotland by order of King Edward I of England, during the siege of Stirling Castle, as part of the Scottish Wars of Independence.
How tall is the Warwolf?
According to modern estimates, the trebuchet would have risen to a height of 300 to 400 feet. It could effectively raid stones at a wall 200 yards away, hurled at a speed of 120 miles per hour. The Warwolf was a siege engine used by English armies during the Scottish Wars of Independence.
How big was the Warwolf trebuchet?
Modern estimates claim that the new trebuchet was 90-120 meters tall (300-400 ft), and was supposedly able to hurl projectiles at a speed of 190 km/h (120 mph). It could effectively toss stones weighing 135 kg (300 lbs) from distance of 200 meters (218 yards).
Are trebuchets effective?
The counterweight trebuchet could consistently deliver heavier munitions at longer distances than its predecessor. The trebuchet was such a successful piece of engineering that it solidified its place as the superior siege engine — far more powerful and reliable than the inferior catapult.
What materials were used to build trebuchets during medieval times?
The Trebuchet A trebuchet used a counterweight (rather than the torsion of a rope like in a mangonel) made from stone or metal plating to spring a single arm and propel a heavy boulder towards the enemy. The arm, attached to a metal axle and greased with animal fat, was wound tense by a winch.
How long does it take to reload a trebuchet?
Trebuchet Base Statistics Level 1 Damage 385 per charge Range 1,100 meters Reload 3-23 seconds.
How long should the rope be on a trebuchet?
The sling harness length should be about 3/4 the length of the glide track, slightly shorter than the length of the short arm, or 80% the length of the long arm.
How much counterweight does a trebuchet need?
Large trebuchets of this type would typically feature a counterweight roughly ten times the weight of the projectile, which would put War Wolf’s counterweight in the neighborhood of 1.5 tons!Oct 11, 2017.
How do you make a small pumpkin catapult?
Install bungee cords through the eye bolts. Hook one end of the bungee cord through the eye bolt on the bottom of the 4X4 and one end to an eye bolt on base. Put 3 bungee cords on each side. Pull back the catapult, load it with a pumpkin in the bucket, and launch!Apr 18, 2017.
