Coasters with high G's

[Vekoma Fan Boy]

I thought/heard that positive G's over 6 would make your eyes gouge out of your head and your nose bleed, I didn't make that up, I heard it on a coaster programme.

 

Anyone know of any other coasters with high G's like this?

Positive G-Force Tolerance

 

The human body can usually tolerate about +9gz with the aid of a protective suit.

Positive G-Force becomes uncomfortable for the human body at +5gz.

 

At 1gz, humans exhibit no ill-effects except for gradual ageing as this is the natural level on earth.

At 2gz, facial tissue sags and hands feel heavy

At 3gz, movement is difficult

At 4gz, visual symptons and slowed awareness

At 5gz humans are at risk of loss of conciousness

 

When under high positive G, blood is being forced from your head to your feet so you 'Grey Out'

 

Negative G-Force Tolerance

 

The human body exhibits alarming symptons at just -2gz and on a roller coaster a level higher than -1gz would be considered dangerous.

 

At -1gz, humans exhibit a sense of pressure in their head

At -2gz, there will be a severe headache, nose bleeds and swelling of the eyelids

At -3gz, Eyes will bleed, vision will fade, eyes will feel as though they are popping out their head

At -4gz, mental confusion and unconiousness

At -5gz humans are at risk of losing their eyeballs and death.

 

When under high Negative G, blood is rushing to your head and can cause very serious 'Red Out' and cause your brain to bleed.

 

You got it mixed up.

Moonsault Scramble pulls 6.2G's, but it's no longer operating.

This thing got me curious. What the hell is a Pretzel Knot?

It was a shuttle coaster with 2 Deja Vu-esque towers (minus the fact that it was a sitdown).

MindBender at SFOG pulls 5.8 G's.

 

What would happen to an asthmatic person who is 265 pounds and goes through one of MindBenders loops?

Most costers top g force is around 4.5

 

I've yet to ride a coaster that makes me feel like blacking out...

 

PLUS: High g forces is also good for another thing; longer drops! think about it.

 

Sheikra's VERTICAL drop, is probaly around 100 feet. (i'm talking truly vertical, not going into vertical) but probaly pulls around 4-something g's

it's got a 200 foot drop

[weeow]

It may be 200 feet high but i don't think it's a 200 foot drop. Mindbender at sfog pulls that much? I tried to put my hands up through one of those loops and my elbow got pulled down and slammed against the side of the car.

The height of the drop still has little relevance to how many g's it actually pulls, what matters for g-forces is the radius of the turn, in just about every case. You can be going 30 mph through a helix and be fine, but if that turn has an obscenely small radius like 5 feet, and that will generate higher forces. Likewise if you have a 100 foot drop, not all that exciting, if you shorten the bottom of the hill it starts racking up the g-forces. G force tolerance also depends on which direction, including along the length of the track, which is why pretzel loops seem so intense because the human body isn't built to handle high g-forces in that position, which may also explain why Dodonpa is described as being kicked in the chest.
