Matt MacDuff: Loop Of Doom - Video
@RVD604: you are right, going slower or making it wider, but I think that he feels safer going at match speed,so maybe making a shorter "roll in" would be an option to obligate him to go at the correct speed.

He would have to make it wider in order to make it ridable.

Matt MacDuff: Loop Of Doom - Video
@RVD604: Let's make it in order. What happened? Matt rode this loop, but the (centripet) force was too big. What can yo do to lower the centripet force? 1.- Lower the speed. This has a limit, if you go too slow you will fall down 2.- Change the geometry of the loop a) change the height, Matt wants to ride a 40ft loop, so you CAN'T change the height because that's the fucking purpose of the stunt, ride a 40ft loop. b) change the curvature, if you make the loop more wide it will have less force. why he uses this shape and not a circle? because the force that you fell is pushing you towards the loop (the g's he talks about in the interview, the centripet force I have been talking about) depends on two things, the curvature radius and the speed that you are going. More Speed -> More force More curvature radius -> Less force This shape makes the centripet force constant, when you go up in the loop you start going slower, but the radius of cuvature gets smaller to compensate your lost of speed making the force constant. That's why is wider on the bottom, because you have more speed.

@RVD604: yes, and one parameter was the height, so the only thing that you can change is the curvature

Did you ask someone physic related about the loop? You went for the chlotoid loop instead of the hot-wheels loop, so clearly you made some research. It's not hard to calculate what will be the centripet force, can you share the dimensions of your previous succesfull loops? (a picture with some reference would work fine, i.e you standing next to the loop and how tall are you)

@RVD604: the height is fixed. Matt wanted to ride a 40ft tall loop, so you have to change the diameter.
