Making a Mechanical Sine Wave in Lockdown

What is this mysterious steampunk creation roaming through the jungle? It seems to be drawing perfect sine waves with little to no effort – how can such a machine be created?

Watch as Tom Rocks Maths intern Joe Deakin attempts to make a machine to draw sine waves for him, using only things that he can find around the house! As you’ll see, it was quite a challenge to get it all working but Joe seems to be pretty pleased with the result.

Joe originally made the machine a year ago to try and understand the sine wave and this video is a recreation of that process. We hope you enjoy it!

Next up, Joe has set himself the very difficult and entirely different challenge of making a mechanical cosine wave machine…

Produced by Joe Deakin with assistance from Dr Tom Crawford at the University of Oxford. Joe is an undergraduate student studying Maths and Philosophy, and Tom is an Early-Career Teaching and Outreach Fellow at St Edmund Hall: https://www.seh.ox.ac.uk/people/tom-crawford

Thanks to Tom D and Adhi for helping Joe to put the video together.
