Screw
According to the AI overview, a screw is an inclined plane wrapped around a cylinder. This makes me wonder why an inclined plane by itself is a machine, yet is also listed as a machine when it’s combined with a cylinder, i.e., is a screw. I’ll find out when I get to the inclined plane section, but for the record I am curious.
When an inclined plane is wrapped around a tube shape, the result is a really long stretch of plane, significantly longer than the tube. This can be tested by taping one end of a piece of yarn to the cardboard from a roll of paper towels, wrapping that yarn repeatedly around the tube until it reaches the top, then measuring the length of yarn from start to finish, compared to that of the tube (around a foot at a guess).
A screw works by trading all that distance for force. Screws can also turn rotational motion into lifting motion. That means that screws are useful for holding things together or lifting things.
