Hi /sci/, I hear you're smart. If the stop request cord

>not physically connected
You are in a universe with no forces and have sent signals via teleportation.

I mean there's no wire running into the wall or anything. It just looks like a cord strung up on some rings. How does it work /sci/?

goddamn boy, quit being stupid.

>>7589647
Tell me how it works I don't want to be stupid anymore ;_;

IIRC on my bus the cord is connected to a device on the side of the buss near the front and back, and when pulled signals that a stop is requested.

>rings and a cord

How is this not a physical connection to you? Its a cord probably hooked up to some lever at the front. You pull it it trips the lever.

the cord is connected from front all the way to the back and to the front again
there's glass fiber inside the cord, once you pull it you are making the cord and thus the glass fiber longer
as you may or may not know, light is send trough glass fiber
each X ms a light pulse is sent trough it, as you're pulling on the cord it will take the light slightly longer to get back to the front
this delay is detected by the system that sends the light pulses

There's a simple spring-loaded switch at one end of the cord. It's like a standard push-button, but I guess it's technically a pull-button. Pulling the cord moves the switch and closes a contact. A DC pulse is sent via wire (typically routed under a floor or side panel) to a buzzer or bell, and maybe to the control logic that lights up a light or whatever.

The bus drivers are trained to push a button when they see a hand pull the cord.

The cord is operated by a magical pixie inside the walls of the bus.
