inboard ratios help
(OP)
hi im building new race car and gonna try and put in board suspension on the front. my question is why use ratios like 2:1 and not just 1:1. secondly if i normally use a 250 spring and using a 2:1 ratio do i divide the spring by 2 which would make it a 125 spring?





RE: inboard ratios help
However, the spring required is Mr^2, and the reason is that it concern the change in N per mm, and not the lever ratio only.

RE: inboard ratios help
ie the wheel rate is the spring rate/MR^2
So a 250lb spring @1:1 means you need a 62.5lb spring @2:1
RE: inboard ratios help
Sorry,
just had the formula around the wrong way for the convention you used for motion ratio. In that case wheel rate=spring rate x MR^2.
Spring rate still needs to be 1/4 of original.
RE: inboard ratios help
wheel rate=spring rate x MR^2.
250*2.1 ?????????
