Floating Arm Trebuchet, The Most Effecient Catapult!

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...

Floating Arm Trebuchet (fat) Phun Simulation

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...

Medieval Engineers: Floating Arm Trebuchet, Modern Trebuchet Design

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...

5 Arm Murlin Trebuchet Trials

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...

Modified Floating Arm Trebuchet

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...

My Floating Arm Trebuchet Project

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, ...

Trebuchet Sling Release Mechanism Guide

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...

Floating Arm Trebuchet-with Plans In Description

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...

Mini Trebuchet (catapult)

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.
