From Software Engineer To Catapult Engineer

For my birthday, I was lucky enough to get Da Vinci Catapult kit. Now for those of you who are unsure as to what this actually is, it’s a small working scale model that’s actually pretty powerful! 

Let’s talk Physics

Ugh, not physics, please anything but Physics. So this is a single armed catapult, Da Vinci did actually create a double armed one. Now the Physics behind this is solely based on the tension of the rope (or in my case string) on the catapultis what allows it to fire with so much force and much less effort than the standard catapult that we all know and love from the first century of the common era (that’s AD for all of you who still live in the past).

But seriously, I could probably do a lot of damage with this

In fact if I was hooligan who walked around in an ape-like manner, then: one, I probably wouldn’t be able to build this, because I:d be too uncivilised and wouldn’t possess enough brain power to follow instructions and two, if by some miracle I managed to get my hands on one of these, I could go smash some windows with it. 

So, how does it actually work?

Okay, so we’ve established that there is tension in the ropes on either side. There is a block wood which stops it from moving and holds the tension in the ropes. If we remove that, the tension releases converting all that potential energy into kinetic energy. Absolutely fascinating

And of course, it is a marvel to look at

It just took me forty-five minutes to build. Here are some more pictures of it and a video of it in action!
