Last post by Cas - April 17, 2024, 02:30:25 AMAbsolutely inhuman, ha, ha. Well, I hit some numbers wrong, but I assure you that you need a very large loop still for that speed. If it were possible to build a stable loop big enough, it would be a lot easier to do the stunt.

Last post by Duplode - April 16, 2024, 11:58:38 PMWe gotta divide rather than multiply by 3.6 when converting to m/s. That gives a speed of 109.5 m/s and thus, by the formula above, a (still quite scary!) acceleration in g of 1223m / r.
What is the radius of a Stunts loop, though? Let's stick with the basic conversion factor for the in-game physics: 1 track tile = 1024 3SH units = 205 feet. Like most roller coaster loops, the Stunts loop isn't perfectly circular; however, the upper half is close enough for using the extreme z coordinates (that is, along the direction of the track) for the radius:
That means a radius of 449 3SH units, or 89.89 ft, or 27.40 m. The acceleration, therefore, would be an extreme 44.64 g!

Stunts Modification Projects / Re: Color changing of the need...
Last post by Cas - April 16, 2024, 10:30:41 PMThanks, Zapper! Yes, I was sure I had skipped it! It had to be there. I've already obtained it from the CCC Stunts download, but I knew it had to be in the forum. Cheers!

Last post by Cas - April 16, 2024, 10:29:14 PMWow! Amazing! 
Well, acceleration is v squared by radius, so for 245 mph, which are 394 km/h, that is, 1418.4 m/s, we have a = (1418.4 m/s)^2 / r. If we want g force, we need to divide that by gravity acceleration on the surface of Earth, roughly 9.81 m/s^2, so:
g = (2011858.56 m^2/s^2) / (r * 9.81 m/s^2) = 205082.422 m / r
It still depends on the radius. If you don't want to die, but want to make sure you'll get some grip at the top (since actual tangential speed won't be constant), a maximum of some 6g, like in the video, sounds like a safe bet. To make that g value, you'd need a loop to be some 34 km in radius, ha, ha... That square in V really makes a difference!
With a loop that big, the good thing is that it'd be much easier to drive through it and speed would be a lot more constant than in the video, so g force would also be more stable. Then you can afford a bigger loop to have a lower max g as well. The problem is how you will build such a huge loop strong enough to withstand itself and the car.
Duplode, you're better a math guy than I... Let me know if I'm doing my calculations correctly, ha, ha

This makes me wonder: what are the G forces of an Indy / GTO reaching 245mph in a loop?

Hi Cas,
