Now, I'm a level 8 Sword and Shield Warrior Inquisitor, and my entire party is level 7 (Sera, Dorian, and Cassandra). And I get to the last trebuchet fight, where I gotta slowly turn the trebuchet as waves of enemies keep coming.
I keep dying. There's no way around it. I'm a bit under-leveled and there are WAY too many enemies around. I've retried it so many times that at this point I don't care how I win, I just wanna win (tried luring enemies one by one back into Haven, heck even up the mountain on the side of the trebuchet, to no avail)
Getting the measurements for your trebuchet is one of the most important steps. Below is a picture of my initial design, with the measurements that I ended up using.
Part A - This is the counterweight and consists of two different pieces, pieces A1 and A2. The more A2 pieces you have, the wider your counterweight is and therefore the more weight you can put in.
Part B - This is the "arm" of the catapult and has two joints, one where it meets the counterweight, and one where it meets Part C
Part C - Raises the throwing mechanism off the ground. Has one joint where it meets Part B. If this part is too short, the counterweight will hit the ground instead of sliding smoothly through the movement
Part D - Provides stability and keeps the trebuchet from knocking itself over. The longer it is, the more stable the trebuchet
Part E - Adds necessary strength to Part C
There are six holes that need to be drilled in order to complete the throwing mechanism.
Two of the holes need to be drilled on the "arm" of the Trebuchet (Part B). The first hole should be 2-3 inches away from the wider end. I used a 13/16 inch drill bit to make this hole. Using the same drill bit, drill another hole approximately 10 inches from the wider side. It'll take some force, and maybe a couple pounds from a hammer, but shove a piece of 3/4 inch PVC pipe into each of the holes. Pre-cut these pieces of PVC so that they are flush with the cardboard on either side. See first picture for clarity
Drill 5/8 inch holes 2-3 inches from the narrow end of Part C. See second picture for clarity.
Drill 5/8 inch holes into the top of the counterweight and glue the washers around the holes. See third and fourth picture for clarity.
Now cut your 3/4 inch axle into a six inch piece and a 15 inch piece. Take the six inch piece and slide it through one side of the counterweight, then through the "arm" of the trebuchet (in the hole closest to the edge), and through the other side of the counterweight. Take your 15 inch piece and slide it through Part C. Slide the rest of the rod through the other hole in the "arm" and then through the hole on the other half of Part C. See fifth picture for clarity.
Now it is time to attach your supports. For Part D, cut four pieces (four layers apiece) that are 41 inches long. These pieces should be 6 inches wide on one end and 3 inches wide on the other.
Glue these piece to the bottom of Part C as shown on the second picture.
Part E are by far the most important supports. I tried firing the trebuchet without Part E and it had so much power that it ripped off all of the supports I had just put on in Part D.
Cut out pieces that are 4 inches wide and 27 inches long. You will need four pieces that have 12 layers each. Glue these pieces together. Trace the exact angles you will need on both the ends onto each of your pieces. Cut the pieces to shape and glue them in place. See pictures for clarity.
The Middle Ages, spanning roughly from the 5th to the 15th centuries, are a romantic age, spurring forth tales of knights in shining armor fighting over castles protected by high stone walls and drawbridges over perilous moats. But while one might think all vestiges of medieval times were left in the past, there is one holdover that only seems to be increasing in popularity: the siege engine known as the trebuchet. While medieval times are not known for their technological advances, this clever piece of machinery has had lasting implications.
The ancient precursor of the trebuchet was the stave sling, also known as staff sling, which was a simple sling on the end of a staff for hurling rocks. The catapult, also known as a traction trebuchet, was a much larger version of the stave sling, generally with a group of men used to pull down on ropes that would then propel the object of choice, usually large rocks, at castle or city walls.
The counterweight trebuchet was a double-armed machine that improved on its predecessor. Instead of a group of men pulling down to launch the payload, the machine used gravity and a large counterweight to launch an object. The placing of wheels allowed the machine to move forward and backward with the motion of the arm and swinging action of the counterweight.
The first recorded use of a trebuchet is in Europe in the 12th century. It was the machine of choice for the siege of castles, and far eclipsed the range of the simple catapult. The catapult used potential energy stored in twisted rope to hurl objects. While catapults could be reloaded more quickly, their range was less and their payload lighter.
Trebuchets were very heavy and often built on-site, and were not designed to be mobile, but to lay siege to a castle or city and destroy its protective walls. The counterweight greatly extended the range of the trebuchet so that it could remain far enough from its target to be out of reach of serious harm, but still close enough to unleash its deadly terror.
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. King Edward refused to accept their surrender, however, until after he had a chance to use the machine, which leveled a large section of the castle wall.
Today trebuchets are used as teaching tools in high schools and colleges to learn about load, force, fulcrums, velocity, gravity, and parabolic arcs. They are also used as recruiting tools to lure students into engineering programs. Designing a trebuchet is an assessment of mechanical design and engineering skills. Testing a trebuchet is not only a learning tool, it is also fun.
While in medieval times trebuchets were used to hurl stones, manure, and even the bodies of enemies, today they are used to hurl pumpkins, cabbages, and the occasional piano or car (like in this video of the annual Punkin Chunkin). Whether used as a teaching tool or just for fun, trebuchets have proven to be a timeless engineering marvel.
i'm working on a quick sketch for a floating arm trebuchet i'm making in an engineering class and need help selecting and using the correct mate tool in the on shape assembly tool. i need the axle on the end of the throwing arm to slide up and down within the rectangular slot running up and down the center of the main truss. here is a link to my Onshape document for reference, any help is greatly appreciated
A trebuchet is a World vs World siege weapon that fires explosive shots or tainted cows over long distances of up to 10,000 units. The primary purpose of trebuchets is to destroy walls over distances too large for a catapult, although they can also deal reduced damage to gates and infantry, and cause a knockback effect. Alternately, the trebuchet can be loaded with tainted cows, which deal no damage but create a poison cloud.
Superior trebuchets deal 50% more damage than regular trebuchets and require an additional 20 (120 total) to build. They are built with Superior Trebuchet Blueprints, which are made in the mystic forge.
Guild trebuchets are functionally the same as superior trebuchets. They can be built with Guild Trebuchet Blueprints, which are purchased for 12 + 3 from a guild commendation trader or crafted by level 400 Scribes.
I was wondering if it is possible to animate the Trebuchet in such a way that the projectile of the trebuchet actually leaves the sling and makes impact against a wall at a certain distance say x='some constant'.
Very interesting! I will be continuing to make a complete model in Mathematica including the 3 phases of the projectile,s flight: 1. The constrained sliding, 2. The slinging on the trebuchet and 3. The free flight under gravity. As mentioned before: the sliding is essential to gain projectile range and will improve substantialy your trebuchet,s efficiency.Good luck and keep on experimenting!
Erik's Demonstrations help us to understand the physical model and trebuchet dynamics.As a organizer, I draft a Mathematica notebook to introduce trebuchet topic for our young players.I attached notebook format, see attachment. (Sorry, only Chinese Version).
Indeed, this would avoid the constrained phase when the projectile is sliding on the floor. But this is not how the real trebuchets worked. One can prove, as Siano did, that the range and efficiency is much higher when you have this initial sliding phase.By the way yr idea of a pit to avoid the constrained sliding is the intermediary solution mentioned in Siano's paper (page 12)
Thank for the SystemModeler Example. However, Catapult is a little bit different design from trebuchet.Catapult is a kind of device allow elastic element, like spring, inside the system to reserve energy, then release a projectile.Trebuchet is actually anther stone projectile machine, which convert energy purely from potential energy to kinematic energy.We stay with trebuchet for our competition this time. becasure, the stiffness of spring is hard to measure and compare.Anyway, If SystemModeler can predict catapult, it should be able to predict trebuchet as well.The problem is I don't know how to best use SystemModeler and lack of know-how of trebuchet, either.
But a real trebuchet is more complicated than is depicted in all the above (including my own demonstrations!)If you look at the paper "Trebuchet Mechanics" by Donald B. Siano and at this design from the paper:
