I was riding the Paratrooper wheel at the local carnival with my son tonight & was wondering if anyone knew how to figuring our G-forces.
The wheel looks like a small ferris-wheel tilted at about a 50 degree angle.
It is approx. 32-35 feet in diameter with 10 swiveling seats.
At full blast it takes 5 seconds for 1 complete revolution.

Need to know (a) the mass of both of you and (b) the angle that your seats were from the vertical when at maximum speed http://ubbxforums.ubi.com/images/smiley/mockface.gif

No you don't, G is a "per unit of mass" measurement, mass cancels out in the calculations. The angle can be worked out from the available data with some simple vector calculations. Give me an hour or two and I can probably come up with an answer (I'm REAL rusty on this stuff http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif)

Result:

1.68G tops (taking minimum diameter of 32 feet) at the bottom.

Larger diameter means less G.

Give me a couple minutes more and I'll give you G at the top of the loop also http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Edit: Minimum G at the top of the loop is about 0.65G

ok i have mathmatical question as well.

If Truck A is traveling at a constant speed of 75 mph. over a distance of 75 miles.....
how fast is truck A traveling per min.(60 Seconds).

or to rephrase the question.

@ a consistant speed of 75 MPH what is the ditance traveld by truck A in 1 min.

One & a quarter miles. Just over 2km. 6600 feet. 2200yds. 100 chains. 33 and a third furlongs. And if I have my conversion factors right, 1,676,400,000,000 angstroms.

75 divided by 60 gives miles per minute

Thanks Tully,
I thought it was a lot more than that,something like 3 Gs. If it's only 1.68 then I can't imagine how jet pilots can pull 9 Gs or more even with suits. I guess I'm getting old. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif
