bonus fun fact - the etymology is connected - "axle" comes from older words for "shoulder", or "armpit", which survives in some regional Englishes as "oxter" - the connection is apparently that you'd carry a person by putting their arms up and linking at the shoulders, much like an axle is how wheels carry a cart.
