We are three guys from Sweden who made a Floating Arm Trebuchet as a school project. This is the most effecient catapult design known today. We managed to throw a 0.5 kg (1, 1 lb) projektile 110 meters (361 ft), this gave us an effeicency of 41 %. Our counter weights were made out of concrete and ha...

This is a brief tutorial on trebuchet physics and useful tricks to make your trebuchet throw farther. Much of this isn't obvious if you're new to trebuchets and I overlooked many of the key energy transfer methods when I was starting out. Hopefully, this will help you optimize your trebuchet In this...

This is the F2K style floating arm trebuchet that our team built for a pumpkin throwing competition. Spokane Falls Community College puts on the contest every couple years...
Who can honestly say that they don't need a trebuchet for home defense? In this episode of Some Assembly Required, Shawn Wasserman designs and builds a trebuchet big enough to throw a pumpkin. Warning - graphic images of exploding fruit. If you're wondering what this software is, it's called Autodes...
This video has been captured using FRAPS in the Phun 5.28 application. I have modelled this modern trebuchet in order to demonstrate to myself that I have understood the design properly. The most problematic was the sling, I made it using a free form tool in combination with two tight strings, one t...
Today we have a look at a modern design for a Trebuchet that still works with Medieval Engineers parts. The Floating Arm Trebuchet. Really hope we get the hooks and sling parts to make trebuchets work properly soon because this should be a super efficient design. For now though it's a kinda weak cat...
Shoots a golf ball 560 feet (my latest numbers are over 1200 feet - see 1200 foot+ golfball trebuchet). These are the first shots from a new 5 armed MURLIN (multi-radius linear nodes) trebuchet designed to shoot golf balls. Counterweights progress from 7.5 to 30 lb. Device is designed for 37.5 lb ma...
My office does a good job of having fun activities for us during the year. This is the first year that we've had a catapult contest though, and for the first time I had nothing to do with coming up with the idea. Here are the rules. 1. No ready-made kits 2. Catapult devices cannot exceed 4 feet in h...

Construction and testing of a floating arm trebuchet for Logan's AP Physics class. During our testing, the trebuchet launched golf balls about 170 ft with 15 pounds of counterweight. For fun, we also used it to lay siege to a gingerbread castle. I bought the parts for the top piece at Lowes. The tur...

Building a catapult is simple, using a block of wood as a base, a plastic spoon as the arm, two push pins and a rubber band as the torsion energy. Assemble a simple catapult, using mini marshmallows as ammunition, with a demonstration from a science teacher in this free video on science. Expert: Col...
Slow motion of trebuchet action. Treb is 15' in height with 12' tapered throwing arm and a 400 lb counterweight optimized to hurl objects 300'. Plans for full size trebuchet available at...
A floating arm trebuchet my son designed and built. * The trebuchet site has been updated with everyone's welcome feedback. Come check it out - * The treb is all wood and steel. Even the wheels in the mechanism were out of pine and made on the tablesaw and router. Projectile is a tennis ball filled ...
Troop 1935 of the Woodlands, Texas, designed and built this floating arm trebuchet for the Annual Pumpkin Chucking Contest. They won the competition through their innovative design, determination, and teamwork!...
This is the floating arm trebuchet I made for the final project in my AP Physics class. This took about a month to make from first design plans to final testing. It is 12 feet tall, about 8 feet long, and less than 2 feet wide. It is made mostly out of wood, except for the throwing arm, weight bar, ...
This video gives an overview of two types of sling release mechanism. It first studies the standard angled pin release in detail, which is triggered by sling angle. It then shows how you can do an arm angle triggered release, as used in a multiple rotations trebuchet. Hopefully, this will give fello...
This floating arm trebuchet was made for a school project. It's extremely powerful. Although the longest throw was 206 feet with a baseball, The trajectory was WAY too steep and went something like 100 feet in the air. After we lower the trajectory I'm guessing about 350 feet with only about 50 poun...
Building a trebuchet requires a wooden base, sides, masking tape, washers to use as weights, a glue gun, stapler and a push pin to create a table-top throwing arm. Assemble a miniature trebuchet with a demonstration from a science teacher in this free video on science. Expert: Colin Kilbane Contact:...
My floating arm trebuchet, built following a slightly modified version of Ron Tom's Plans. Still calibrating, but the range is in excess of 225 feet, my first throw. some stats: CW mass: 10lbs+axle height: ~1 meter projectile: golfball range: 225+ feet All shots in this movie are intentional misfire...
This is the simulation we used as base model for our Floating arm trebuchet. The simulation itself has an efficiancy of 91%. So almost all energy is transmitted to the projectile. The counterweights is on 40 kg (88 lb) and the projectile is on 0, 5 kg (1, 1 lb). the projectile is thrown around 250 m...
Slow motion launch of a trebuchet i designed and built Southern Poly State Uni. farthest throw was about 300ft with a golf ball. the criteria were: less than 25 lbs, less than $25, and less than 4ft. it won the range competition...
As a response to a request i have made a video showing how to create a floating arm trebuchet. DO NOT I REPEAT DO NOT MAKE THIS TREBUCHET WITHOUT A FIRING MECHANISM. I created a trapdoor like device for mine. there are many different types of firing mechanisms so you can design your own...
We built two small trebuchets for a school project a couple years back. They use a cigar box filled with lead shot for a counterweight, are made of oak, and use a wheel and free-hanging counterweight design. This allows the trebuchet to function with a smoother motion, and more efficient use of the ...
