@engineezy: This was supposed to draw a star ••• But I accidentally discovered that just by changing the ratio between the stationary pulley and the pulley that spins the second linkage, you can drastically change the output path of the mechanism. The start is created with a 2.5:1 ratio, while the triangle is created by a 4:1 ratio, and the oval comes from a 2:1 ratio. The belt tensioner system was designed to use the same belt size for all 3 pulleys. ••• #engineering #mechanicaldesign #engineeringstudent #mechanicalengineer #mechanicaldesign

matt :

thats a funky way to build a spirograph

Ryanxiety :

Every generation is fated to reinvent the spirograph

Elly :

that's an elliptical not an oval

5-0-0 GlueGunner :

Is this how rides at fairs work

Velmore :

Ratio 2:5 me

This was someones math phD thesis once.

Engineer discovers Fourier transforms

Leffe :

But is it legal??

Alappi :

whats the point of this machine? 🤔

hi :

What about 1:1

jdjsoao :

plese use pi as a ratio

QoBi :

why was this unexpected?

ImmortalSnail 🐌 🇨🇦ᖭི༏ᖫྀ :

You did it! Is there any shape you can’t draw?

hyprspd_ :

I'm assuming this was inspired by Fourier series

Unexpected how?

desertfresh :

duh?

Brannigan73 ♛ :

1to 1 please

🦇 Harkness.the.monster 🦇 :

What about 3:1

Hydro :

Do a ratio of pi:1
