This might be a noob question but, how do you make a stretched hinge?

Hey, why wont this work
It was workin a month ago!

You can use a stretched hinge, with a key binded to it so it can brake and therefore transmitting power.

You know those dark blue triangles on the blue circle? If you look, you can see multiple 'clones' of themselves.

By calculating the area of the cylinder.
