You saying I ain't eloquent enough to be an Astronut? :)

Another wiener!!!


"wheels of same radius at start and end of the sequence will spin at the same speed."

Visually and logically, same size wheels should rotate at the same speed when one is the driver and the other is driven by it. What complicates things is not knowing the sizes of the idler wheels, so you have to assume they will result in cancelling each other out or fool yourself into believing that they're going to have different angular speeds - unless you can do the math to prove it to yourself.

Easiest thing to do is to apply the law of gearing and assume each wheel is a gear with a single tooth, and then do the calcs for a compound gear train. Your result should match your gut instinct that both wheels that are the same size will spin at the same speed. But again - to do this you'll need to know the diameters of all the wheels.

I figure that since they didn't specify then it was a safe assumption.

Totally wrong comment in an interesting thread

And a third winner!


I only got two our of three and one of those I got I just remembered from another article. :oops:

Maybe have to settle for “space cadet”. :D :up:

In your next life you could always try to get admitted to the Star Fleet Academy
Well something similar.

No doubt in my mind...some day in the future, we will not have NASA, Russian, Chinese a.s.o. We will have on Organization.

^ I agree, but without England i guess :O:

Seriously, be it a hard contact with some asteroid or a debatable what was called a "contact of the third kind", mankind will sooner or later have to come to terms with itself, with one mankind and an existence without artificial nations. There is of course the other "branch", the possibility of fading awy and dying out.
Before WW1 there were not even borders in the sense mankind has it today, clearly not an achievement.

:D Actually with the creation of the US Space Force that could become an official rank! :)

"Would you like to know more?"

"Would you like to know more?"

This is "Starship Troopers", not "Space Cadet" i know :O:

Concerning Space Force, the general term is "Guardian".

E-1 through E-4 are referred to as Specialist (1,2, 3, 4)

After that it follows the Air Force rank names.

:nope:

I hope they kill this before it gets out of control.

Nothing wrong with a Unified Command of US Space Command like we used to have.

Having a Space Force now is like proposing an Air Force in 1907, in my opinion.

All due respect to Mark Kelly but there ain't no air in space, so the Navy, Marines, heck even the Army, have just as much claim to novelty of military space duty as the Air Dales.

Funny. USN has a "Naval and Space Warfare command (aka SPAWAR) who are now called NAVWAR because of the new space cadet force.

Catfish 04-19-21 07:37 AM
Space warfare, what else. So the US are not the good guys?
