Well, I've got some real estate in Florida.

Sweet, waterfront by the bridge, right?

 

That would be the Normal force. Much like the ground forcing up on your feet equal to the amount your feet press on the ground due to weight.

 

Well, realistically I'm gonna need to sell the 7. I'll be graduating college and getting married in a year, so I need to cut the project herd down to just the RX-2. If anyone's interested, let me know.

 

Dear Mr. Webster, After the smoke from myears cleared the room i still didnt understand. now mybrain hurts

 

What you're describing is the force of gravity. When an object is moving in a centrefuge the forces within can far exceed the force of gravity.

Case in point - when you ride a roller coaster and go through a loop, and you reach the top of the loop, you do not feel yourself drop down against the harness pulled by gravity but rather you press into your seat.

If only centripetal force existed, you'd fall into your harness. If only gravity existed you'd fall into your harness. But you don't. Because your body wants to continue in a straight line, but the coaster is moving in an arc, you press into your seat as the centrifugal reaction to the centripetal force.

 

From my PChem text:

"A particle revolving at constant speed in a circle is undergoing an acceleration directed toward the center of the circle called a centripetal acceleration. Just as a marble on a merry-go-round tends to move outward, so the protein molecules tend to sediment outward in the revolving tube in the ultracentrifuge. If we use a coordinate system that revolves along with the solution, then in this coordinate system, the centripetal acceleration disappears, and in its place one must introduce a fictitious centrifugal force acting outward on the particle."

This is why toilet water goes down counter clockwise in Australia and may have something to do with why Crit's car isn't working right.

Crit you need to replace your ficticious centrifugal force that everyone thinks is pushing the apex seals against the rotor housings with some MMO, this stuff is real and always works.

actually the toilet water thing is a result of another phenomenon called the Coriolis effect. This 'effect' states that toilet or drain water will spin one way in the Northern Hemisphere and the opposite way in the Southern hemisphere due to the effects of the earth's rotation.

In theory that's all well and good, and the effect does occur in wind patterns, cloud movement, etc. but the drain thing is an urban myth. Water is equally as likely to go clockwise or counter clockwise regardless of what hemisphere it's draining in.

 

But Manntis how is that effected by chaos?

 

I've seen water drain both directions. Infact, one time I sat and stared at a large basin sink and watched as it went from one direction to another (it was almost empty at the time). Sometimes two 'whirlpools' would form. Other times, an air 'tube' would form in the whirlpool and make a strange sucking or gurgling sound.

 

I finally agree with Mantis about the toilet, but let‘s revisit the rollercoaster.

Pretend that you are riding the PHYSICS NIGHTMARE at 6 flags. At the very top of the loop, a Klingon battleship blasts the ride, vaporizing any inorganic material.

The Question is, what path would your now-free-floating naked *** follow?

Option 1: Centrifugal force exists. Since this force is pushing upward on you with a magnitude greater than the force of gravity, you would accelerate straight up, probably forever. The good news is that the universe is doughnut shaped, so if you travel through space-time along the same vector forever, you will eventually get back to where you started.

Option 2: Centrifugal force doesn’t exist. Your body is influenced only by its inertia and gravity (ignoring wind resistance). At the instant the coaster is vaporizes, you are traveling on a path tangent to the arc of the circle (straight ahead/horizontal). Since gravity is acting on you, accelerating you toward the ground, your position will follow a parabolic trajectory, and your velocity will turn linearly from straight ahead (horizontal) and approach vertical asymptotically. Your final velocity, the speed at which your naked *** hits the ground, will depend on your initial velocity, the height of the ride, variations in the local gravitational constant, etc.

Try and figure out the answer. Extra Credit for an explanation involving derivatives with respect to time.

Crit, I'm really really sorry...

 

"but the drain thing is an urban myth. Water is equally as likely to go clockwise or counter clockwise regardless of what hemisphere it's draining in."

-Manntis

That's strange, my toilet always goes clockwise. I wonder if it's something about my urination patterns? Maybe I get it spinning clockwise a little, establishing a centripetal acceleration that influences the toilemetry flush dynamics.

As far as Feds options go, I'll pick Option 2, since my PChem text book clearly states that centrifugal forces are "fictitious".

So to answer your question Feds, your Klingon-blasted free-floating naked *** would fall to earth under the inluence of gravity and its newly assumed inertia, a parabolic trajectory that would land you somewhere in the middle of Atlanta in about three seconds.

Option 2 removes the motive force imparted by the rollercoaster centrefuge, but allows the motive force of gravity to continue. Whenever you remove one motive force but keep the other constant, of course the other, no longer being overcome by the first, wins.

 

Now we are getting to the heart of the matter. The force imparted on the person by the roller coaster is not outward (centrifugal) but inward (centripetal).If the roller coaster vaporizes, you continue moving on a path tangent to the loop. However, if the roller coaster continues to exist, your velocity changes from <- at the bottom of the loop to ^ on the front side to -> at the top to \/ on the back side. Since acceleration is change in velocity over time, this means your acceleration needs to be in the centripetal direction. And, since acceleration is directly proportional to force, the force exerted on the rider by the car, and the on the car by the track needs to be inward, not outward.If we are assuming constant forward velocity around the track (not a good assumption, but not bad), the force HAS TO be inward.

Oh, and your toilet swirls in one direction because the water outlets are pointed in that direction.

Crit: I'm sooo sorry!

 

no - the force of the TRACK is changing direction from linear to curved. The force of the COASTER is propelling the passenger along the track, pressing at their back. The force of the centrifuge effect is pressing the person down into their seat, more than overcoming the force of gravity that, at apogee, is attempting to pull them down out of the coaster and press them against the shoulder harness.

in a centrefuge no acceleration is required. It can spin at a constant rate and the objects will consistantly press outward against the sides, provided the speed imparts enough force to overcome gravity.

If it was nothing but centripetal and gravitational forces, then a rock released from a slingshot would have momentum pulling it inward to the centre of the swing, not outward to the opponent. David would have hit his own arm instead of Goliath.

 

*goes and finds his physics books from a few years ago...*

Crit, you should rebuild it :-) (we have the technology!!)

Just talk to RB or Atkins and get the parts you need....

I'm not selling my car when I get married, no matter what

 

Yeh Crit, that's one damn nice 7 you got and you need something to keep the 2 company. Everyone who sells a 7 regrets it sooner or later.

 

keep the Sev

 

totally, I just got mine and am not only damn happy, but damn proud to be driving a 19 year old car still faster than the ricers at school

 

Try driving a 23+ year old car that you bought for $300 that trashes the ricers

 

Try driving a 30 year old pickup whose tailgate taunts them with the source of their dismay: "ROTARY POWER"!

i'm driving a 21 year old 7 that i bought for eight hundred and i just smoked a i-vetec in it the other nite -how much does a friggin i-vetec cost?

 

Approximately 20,000 dollars. And for that you get 160 horsepower... That does it, I'm moving to New Zealand. 20 grand US would get me all three generations of RX there.
