Star Trek was heavily influenced by the Navy. It was the Navy in space. The ship itself was named after the carrier.
The ship was commanded from the bridge, had a Captain, helmsman, navigator, engineer, and used torpedoes. The ranks were all USN.
Sorry, Army. Sorry, USAF. The future of human civilization, as envisioned in that series, was based on the US Navy.
Because the future of mankind is being stuck inside a tin can.
Well, I don’t think that was the point of Star Trek, was it?
They managed to visit a lot of strange new worlds. They sought out new life, and new civilizations. They boldly went where no one had gone before.
Kirk himself seemed to have a rather active social life…
I was joking, but with flight times to Mars using the physics we currently understand being measured in months at best, I think the tin can reference is pretty accurate. Not to mention the artificial habitats that we would need to live in there.
Q: Is the shaft hollow...like my TrueTemper framing hammer? I ask that 'seriously' as I was told surfaces compound the strength and keep a shaft light.
I only just heard the driveshaft in the old Pontiac Tempest was a 3/4" shaft (engine to rear mounted transmission).
Q: Also, is the Enterprise's shaft designed with some flexibility in it?
My uncle was abord the Ticonderoga (CV14) during WWII. His mom, my Grandma, told me they were ordered not to speak of their time on board. He didn't.
It remains the most embattled ship in the history of the USN. She earned 5 battle stars.
Should Battle Stars be capitalized?
My first car was a used Toyota and drew a look from him.

I always thought they were "screws" and ideally left the water still.

They call them screws, but they are propellers. I believe the terms are interchangeable.
Here are (apparently) the propellers from the Enterprise:
And another shot of "Big E":
Here are the ones from the Dwight D Eisenhower:
There was a marine shop in Bay Ridge Brooklyn near where I lived trued screws.
Refinished props had the same kind of tooling marks. I recall those being 8-10 feet in diameter.
I had a pal who worked at a wire rope company (Paulson) and if you ever needed any such items, the rule was, "If you can carry it, you can take it home".

Yeah and arent the props 5-6 tons plus each. Simply amazing.
Check out the "rope drive" in the '61 Tempest - the engine was in the front, and the transmission ( as you said) was in the back. They were connected by a flexible driveshaft, which spun at the same RPM.as the engine.
I can't imagine the vibration if one of those props threw a blade.
Screw is the colloquial term, propeller/propellor is the technical term. One of the earliest ship's propellors had a shape similar to a corkscrew. A propellor head is however not a synonym for a screw head.
Each of the seven Emma Maersk E-Class container ships has one 31-foor diameter, 131-ton propellor. Those are the largest ship props ever made. They turn at up to a little over 100 RPM.

It has happened.
I posted this several months ago, and, yes, there was huge vibration when it let go.
I can imagine it was very strong. Our ship hit a deadhead in the Gulf of Alaska and it bent one blade. The vibration was felt throughout the ship. We ran on one shaft until we could get to a dry dock in Tacoma.
The Nimitz-class props are around 25’ tall, weigh 66,000 lbs each of solid bronze, and at full tilt are making nearly 3 revolutions per second.
