## transitions

Talk about ramp building, ask questions

### transitions

if you have a 7' transition on a quarter pipe, would it have to be 7' tall to finally reach vert?

Yep. You reach vert at 90 degrees up from your starting point using the string & compass method. At that point, you would be at the same height as your compass pivot/axis point, i.e. 7 ft.

### Re: transitions

what were to happen if i used a 7 foot elliptical transition would it still have to be 7 foot tall or would vert come sooner?

### Re: transitions

Well, I'm no geometry teacher, but my guess is you could get to vert at any point/height you wanted to with an elliptical curve. I'm not certain it would still be a "7 ft transition" though. As long as you found an arc that provides a smooth launch and re-entry to your ramp, you could make it vert at any height you wanted. I would just be careful that any one section of the curve is not to abrupt. For example, if it "hooked" to vert toward the top of your transition, that may jack up your launches and landings.

Another caveat... I've never ridden bmx on a ramp. Just doin' my best to help.

Good luck!

I am actually a math major and planning to do a little teaching (via websites that is). frankenfender put it pretty well though so i wont bust out any equations. I would recommend getting some graph paper and drawing out curves down to scale. Why dont you want to use a steeper transition (transition length = height or ramp)?

thanks i bmx so its hard to ride a ramp if it has a small transition. it throws you up in the air really fast. its almost scary. i dont want to have a trasition any smaller than about 6' 6" at the smallest.
