How To Build A Floating Arm Trebuchet

Is a floating arm trebuchet better?

A regular trebuchet is a better realistic war machine. However, a floating arm trebuchet is more efficient when built to a size of between one meter and five meters, making it suitable for hobbyists and model builders.

What is the best ratio for a trebuchet arm?

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.

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 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.

How do you find the distance of a trebuchet?

The formula we then used is: MgH = ½ mv^2 + mgh. M is mass of counterweight, g is gravity (9.8 m/s), H is height of the counterweight, m is mass of projectile and h is height of projectile at launch. formula √((d/t)^2+ (gt/2)^2). The d is distance (range), t is time, and g is gravity (9.8 m/s).

Is it legal to build a trebuchet?

Construction Plans Constructing a small catapult for use in your kitchen or back yard appears to be pretty simple. And there are no laws prohibiting the construction of catapults.

How far can a trebuchet shoot?

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 long should the throwing arm be on a trebuchet?

A trebuchet needs some careful measurements for it to be able to work properly. The length of your sling needs to be 4/5ths the total length of your throwing arm. The pivot should be 1/5th of the way up your throwing arm, so that the arm has a long bit and a short bit.

Are trebuchets accurate?

Put simply, a trebuchet could never hit the exact same spot twice no matter how good its operating team was. Admittedly it still was quite accutate and quite an effective weapon during a siege. Some trebuchets teams were so good they could breach a wall or get in under an hour.

Does the length of a catapult arm affect distance?

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.

How much weight can a trebuchet throw?

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. Second, compared with a torsion engine, it’s a fairly robust machine.

What distance can catapult throw?

Catapults can launch things a fair distance — 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time.

How long does it take to build a trebuchet?

Big trebuchets, the heaviest of medival artillery, often had large crews. The War Wolf, built to besiege Stirling Castle in 1304, took 60 men 3 months to build, and towered at least 300 feet tall.

What kind of materials can I use to build my trebuchet?

The first part of the trebuchet we are putting together is going to be the frame. The lumber we will be using is two 28″ inch 2×4’s, two 5′ 2×4’s, two 50″ 2×4’s, and four 58″ 2×4’s. For hardware we used 2″ wood screws. We will also use plywood as support trusses.

How much damage could a trebuchet do?

Trebuchets could launch missiles hundreds of yards in large, lobbing arcs at or even over a castle wall. The best trebuchets fired stone missiles weighing up to 400 pounds—big enough to do serious damage to a castle wall.

How do you increase the distance of a catapult?

How to Make a Catapult Launch Farther Use Bungee Cord Power. Use the tension of bungee cords as opposed to springs to power your catapult. Shoot From the Best Angle. Create an arm break that stops the arm at a 45-degree angle from the floor. Use a Snug Fit. A Sturdy Base Makes a Big Difference.

How do you calculate the efficiency of a trebuchet?

The simplest way to measure the efficiency of the trebuchet is to divide the kinetic energy of the projectile [Equation (7)] by the available potential energy [Equation (6)]. We denote this the energy efficiency.

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.
