Arc Length of Sinewave calc to find amplitude?
(OP)
Hi all,
Im trying to design a sinewave torroid (Im not sure of its actual name but look up Shark Wheels for reference). To do this I am needing to get a specific arc length across a period, by adjusting the 'amplitude' of the wave.
I know the Arc Length that I need to achieve (for 1 period of X to what would be 2 PI) which is 5.3". The length of a period (0 to 2 PI) is 2.88".
How do I work out what the amplitude y would be? i.e. to fit the Arc Length into that length of period?
Thanks
Matt

Gregs answer gives me ~ 0.97" for the amplitude and for my purpose this is accurate enough for now. Ill investigate the more detailed answers when I get to that stage.
Thanks for all your help.
