all right you put a vertical tube as a cocpit, 100 m long

you weight 100 kg so you put another weight over a pulloey 101 kg

1 g will keep you static cause of friction

but 30 g will pull you down so youll feel lets say 10

when you get to the end of the run you do a half tonel over the cocpit cog and voila keep the 30 gs

oh come on the wolrd has to be staged why this things remain unknown with so many people

Wrong forum Raaaid. I expect the physics is wrong too, but I can't understand it anyway.

Are you hitting the bottle this time Raaaid ?? http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

maybe you mean..
Initially 30 g (G-forces ??) and I'm sure you'll feel higher Gs going around the cog http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
That's of course if you're still conscious..

Without understanding anything else you said, let me ask you this:

Why would friction keep you static at 1g, and not at 30g?

because being the pulley 101 and 100 kg gravity will just pull with 9.8N that wont over come friction

think of movie specialist:

they jump a bulding and decelerate from 300 kph to 0 in 5 m space, the size of the cushion

with this method you have a 100 m cushion

you could literally shoot people into sapce at 1000 gs

the concept is very simple:

shoot people to the sky protecting them from the g forces with a 100 m big cushion, the tube with the pulley and the weight

Any volunteers?

You do know that friction works proportionally to the basic force (like weight), don't you?

If friction is able to hold 9,8N when there is a basic force of 1970N (=201kg*1g), then it will also hold 294N (=1kg*30g) when basic force is 59kN (=30g*201kg). In both cases friction is 0,5% of basic force, that's why it would in both cases either hold, either not hold.

I think he's just got bored of the lack of attention his "look at me, i'm soooo craaaazyyy!" posts are getting on the general discussion forum. If you're going to pretend to be crazy to get some attention you could at least be original about it. http://forums.ubi.com/images/smilies/51.gif It's like being at school again, there's always a boring kid that pretends to be crazy.
I'm bored, raaaid. Why don't you make a video of you making one of your contraptions. That might be more interesting.

thanks tinytim got taht one wrong, learnt something for my physics exam on friday but plz answer me this:

an specialist jumps up a tenth floor he lands on the ground and gets killed by 1000 g

he lands on the cushion and he just feels ten g

if you play it backwards the outcome is the same

then why not to shoot people at 1000 g with a mechanic giant cushion of 100 m?

actually i know this is very unknown tech but works, dont ask me how i know it you would think im even crazier

so i know it works i just want to know why

edit:

and i posted here for being aeronautical related, maybe this is a grain of sand that ends rockets and starts aeronautical cannons to reach orbits

You answered your question in your own post:

"why not to shoot people at 1000 g"

well, because:

"(a person) gets killed by 1000 g"

(a person) gets killed by 1000 g"

but he is in a cushion 100 m big so maybe he feels 15

this is an aerospace topic sorry feel free to ignore me

edit:

the ship accelerates at 1000 g in the cannon but the pilot is in a cushion 100 m long so he just feels 15

come on one thing is to pretend not to understand but this is going to far

Surely, theoretically it could work, but I can't see any practical use.

In order to shoot a "ship" to say 1.st cosmic velocity (8km/s) with 1000g, with astronaut inside it only being subjected to 15g, the ship would need to be quite long - about 600 kilometers. And astronaut would still be subjected to 15g for 60 seconds, start at the top and end up at the bottom of a 600km long spaceship.

People already get stressed in orbital launches and those accelerate a lot farther than any 150m cushion.

How long does a 150m cushion last when shot into orbit? The back of the cushion is at mighty speed and
the front moves much slower to cushion the shock, 100x slower and it is 150m long. Cushion will be used
up and 0m long very quickly and then back of cushion collides with passengers at higher than cannon shell
difference in speed and crushes the passengers to jelly.

Ummmmmm. You go first and call when you get there. Okay?

I'm trying to remember one author who had spaceships with huge flat plates out in front made of ultra-dense
material. The passenger capsule rode behind on a stalk. When the ship was not accelerated under drive the
pod was at the end of the stalk. Inside you felt 1G pull towards the floor. Under drive acceleration the pod
would get closer to the big disc and stay at 1 G inside. Of course the amount of power to accelerate a ship
with such mass were dismissed by another miracle but that's what outright fiction is all about, isn't it?

Oh, yes, what a marvelous concept: stuffing a guy with cushions inside a 100m tube and catapulting the thing at thousands of Gs doing somersaults seems so practical and useful an idea I don't know how the guys at the NASA haven't recruited Raaaid yet for the project. Alas, poor Yorick, the world must be really staged.

But I think he should volunteer to crew the first (and presumably only) anti-G corpse-cushion-burrito device in the world. Oh glory glory. Hallelujah.

thanks tinytim i see we cant shoot people into orbit, but what about my original concept:

you are in hte cocpit and theres a 100 m long tube under you

you pull 100 g during one second, youll fall feeling 0 g, youll fall 50 m during that second

now you are going pretty fast and gonna hit the end of the tube, how to avoid this, pushing 100 negative g so youll brake just in time

tell me is not interesting a plane that can make scissors at 100 g while the pilot feels 0

Beyond a curious and goofy example problem, I don't find it interesting but that's just my opinion.

While your concept does negate the acceleration along the vertical axis of the pilot, it's completely useless in the real world.

Furthermore, if your definition of "fall" is movement towards the ground you will be wrong in many cases. The pilot will accelerate down the tube but, since the axis of the tube will not point directly towards the ground except in level flight, the pilot could even find him/her self moving away from the ground even while the aircraft is losing altitude..

Additionally, an aircraft with a 100m "tube" sticking out of the bottom is nothing more than a fantasy.

Have you considered the roll rate required in your scissors example?
