The ballista (Latin, from Greek βαλλίστρα ballistra and that from βάλλω ballō, "throw"), plural ballistae, was an ancient missile weapon that launched a large projectile at a distant target.
The earliest mention of ballista in literature occurs in the Bible, as invented and used under the reign of king Uzziah: II Chronicles 26:15: "And he made in Jerusalem engines, invented by cunning men, to be on the towers and upon the bulwarks, to shoot arrows and great stones withal. And his name spread far abroad; for he was marvellously helped, till he was strong."
Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a prod (the bow part of a modern crossbow), the springs consisting of several loops of twisted skeins. Early versions projected heavy darts or spherical stone projectiles of various sizes for siege warfare. It developed into a smaller sniper weapon, the scorpio, and possibly the polybolos.

Genres: Adult, Sci-Fi,Generally, I followed Heron's Belopoeica and Philon's Belopoeica. However, those sources do not provide all the pieces of information needed to build an exact replica; they lack a detailed description of pedestal of euthytone, the dimensions of its trigger mechanism etc. Therefore, I constructed those parts to the best of my knowledge of ancient artillery in general. As my aim was to design and build a ballista that would look nearly identical to the ancient one, I used mainly gluing and riveting for connecting the material together. Nonetheless, my ballista performance was rather poor; I could not shoot further than 150 m. I ascribe this to the fact that the washers were turned by approximately 110 degrees. I could not twist them more because a 3 cm wide longitudinal crack appeared on th...

This is a rebuild of an ancient siege engine. It was contstructed and tested during a school project. The maximum range of 190 m was achievied with a 0,750 kg metal ball and a firing angle of 45°.

Facebook: http://facebook.com/XboxAhoy Twitter: http://twitter.com/xboxahoy This time, we're covering the Ballista. Unlocked at level 43, Black Ops 2 marks this bolt-action rifle's introduction to the Call of Duty series. The FN Ballista is a Belgian sniper rifle design, developed by FN Herstal in late 2010. It was designed for the US Army's Precision Sniper Rifle program, competing alongside the Remington MSR and Accuracy International AWM, amongst others. The specification called for a high precision, lightweight platform chambered in a powerful .338 calibre round. The Ballista design is heavily modular, with the barrel, bolt and firing pin rapidly interchangeable to fire a variety of cartridges - and in-game, the Ballista is chambered for the .338 Lapua Magnum round. Ultimately, ...
This was one of several projects I built last week for a group of elementary age students. They had a ton of fun building different planes to launch from this ballista. It's always interesting to see what kids come up with. The bow used is a 40lb PVC bow using an ingenious design presented in this video: https://youtu.be/rmxn-nPNhY8 Thanks to everyone who's already supporting me on Patreon!

test firing a ballista built for a school project
Last year I headed the engineering on a TV show where we made a catapulta in 3 days. It needed to be big for TV but also work well, so we followed the sizes laid down in Vitruvius and had advice from Alan Wilkins and Tom Feely and of course used the treatise by Marsden. It was a bit rough around the edges and some aspects could have been better, but we only managed to get off around 6 or 7 shots and in this very short time were shooting bolts 319m. It could have done considerably more. As it stands 319m is further than any other catapulta since the fall of the Roman Empire - so we were pretty pleased. Thanks to Mike Sansom for the film. The original bolts were 1.5m long and this was reduced to about 1.2m which gave the best results.

As featured on http://www.geeksaresexy.net Mark Winkler decided, in infinite wisdom, to spend six months building a full-scale trebuchet. In the next installment of Geeks Are Sexy's series on crazy inventions and crazy inventors, we introduce Mark's brainchild, "Mongo, the Trebuchet." Mongo often launches watermelons, but the 25Gs of force put on the melon as it launches often causes it to burst in mid-air. In the video, Mark throws a 16 pound (7.25 kg) fireball yes fireball about 250 meters or so with 1200 pounds (550kg) of counterweight. (Mongo can handle up to 1600 pounds/725kg of counterweight.) Three things you should know if you try this at home. First, don’t try this at home. Second, these things go a long way – don’t do this near anything flammable. Third, launching fireballs...
I can't stop this feeling
Deep inside of me
Girl, you just don't realize
What you do to me
When you hold me
In your arms so tight
You let me know
Everything's all right, ahahah
I'm hooked on a feeling
I'm high on believing
That you're in love with me
Lips as sweet as candy
Their taste stays on my mind
Girl, you keep me thirsty
For another cup of wine
I got it bad for you girl
But I don't need a cure
I'll just stay addicted
If I can endure
All the good love
When we're all alone
Keep it up girl
Yeah, you turn me on
I'mmm, I'mmm hooked on a feeling
I'm high on believing
That you're in love with me
All the good love
When we're all alone
Keep it up girl
Yeah, you turn me on
Ahaha I'm hooked on a feeling
I'm high on believing
That you're in love with me
I'm hooked on a feeling
I'm high on believing
That you're in love with me
I say I'm hooked on a feeling
And I'm high on believing
That you're in love with me
