How long should the arm be on a trebuchet?
Dan Becker suggests that the optimum arm ratio is 4to 1 or greater. Philip Radlinski explains that as the size of the throwing arm increases, the distance the projectile is thrown increases then rapidly decreases. This means that the shape of the graphed results will most likely be an inverse parabola.
How does the length of the arm affect a catapult?
How does the length of the throwing arm affect the horizontal distance travelled by an object that is thrown from a catapult? Increasing length of the throwing arm, also increases the horizontal distance travelled by the thrown object.
What is the best arm ratio for a trebuchet?
General wisdom has a 5:1 ratio being the norm for a standard trebuchet, although 4:1 is sometimes used. The longer the ratio, the greater the speed that tip of the throwing arm will reach – but also increasing the force required to move it quickly.
What class of people compelled garrisons to surrender?
It was the engineers, men of really quite low social status in comparison, with the great siege engines. It was they who compelled the garrisons to surrender.
Why are long arms better for throwing light balls?
Longer arms can also help throw a ball faster and farther due to the increased centrifugal force they can generate during the throwing motion, according to The Sport Journal. Regardless of the arm length, however, proper warmups and throwing mechanics are critical to reduce the risk of injuries.
How long should the arm be on a catapult?
The long part of the trebuchet’s throwing arm should be around 4 times longer than the shorter side. For example, if the shorter side of the arm (the counterweight side) is half a meter long, than the longer side of the arm would be 2 meters long.
What is the maximum range of a trebuchet?
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).
How much weight can a trebuchet throw?
A trebuchet is a device for attacking fortifications. 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.
Can a trebuchet destroy a tank?
Tanks have flame suppressants that would extinguish any flame that threatened the crew or engine-for the most part and nothing else is really vulnerable. There is no way a tank could be taken out by a trebuchet.
What battle did Lee surrender Grant?
Appomattox Court House
In Appomattox Court House, Virginia, Robert E. Lee surrenders his 28,000 Confederate troops to Union General Ulysses S. Grant, effectively ending the American Civil War.
Is it bad to have long arms?
It is perfectly normal for someone to have arms longer than their body.
What does the arm do on a catapult?
The moment arm of the catapult acts like a person throwing a baseball or a football. A person with a longer arm should be able to throw a ball farther.
What makes a catapult more accurate?
The angle at which the throwing arm is pulled back to will affect both the distance the projectile will travel and also the height that it reaches when in the air. The Trebuchet: The Trebuchet was one of the more accurate and efficient types of catapult used in ancient times.
How far could a trebuchet shoot?
What are the disadvantages of a trebuchet?
Disadvantages. Although trebuchets have greater power and range than catapults, they also have drawbacks. Trebuchets are more complicated than torsion catapults and therefore are plagued by mechanical breakdowns, require more maintenance, more skill to operate and a larger crew.
Counterweights should be “approximately” 75-100 times the weight of the projectile. Swing Arm Lever: The primary swing board is commonly referred to as a swing arm lever, but some will call it a long arm lever or long arm beam. The swing arm lever works well when it is 1.4 – 1.6 times the base length.
Does the length of a catapult arm affect distance?
How long should a trebuchet sling be?
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.
Is it legal to build a trebuchet?
The short, non-answer is of course you can build your own catapult. And there are no laws prohibiting the construction of catapults.
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 far can a trebuchet throw?
Can you legally own a ballista?
Flame Thrower. If you feel the need to throw some fire around, you are legally allowed to purchase a flamethrower under federal law, and 40 states have no laws against owning the weapon. Though it’s restricted in some states, such as California, unlicensed possession is only considered a misdemeanor.
What should be the length of a trebuchet throwing arm?
A good rule of thumb may be to make the length around 3 times longer than the width, which is what I did. It seemed to work out pretty well. The long part of the trebuchet’s throwing arm should be around 4 times longer than the shorter side.
What’s the difference between a traction and a counterweight trebuchet?
This evolved into the traction trebuchet in which a number of people pulled on ropes attached to the short arm of a lever that has a sling on the long arm. This type of trebuchet is smaller and has a shorter range, but is a more portable machine and has a shorter cycle time than larger, counterweight-powered types.
How to increase the range of a trebuchet?
This abbreviated engineering project idea will help you get started with three different ways to investigate what factors can increase the range of a trebuchet: Trebuchet Physics: Use hand calculations to predict the range of a trebuchet based on its dimensions and other variables.
What to do if your trebuchet is not working?
Often times, if a trebuchet is not working too well people look at the pouch that holds the projectile. And while this is always a good thing to do the problem I most often see has something to do with the arm of the trebuchet. Firtst let’s take a look at the very end of the Trebuchet arm.
