Stinger configuration

[lavecchiasignora]

Hello!

I have a stinger configuration and I want to use the same stinger while I want to change the stinger radius. For example: My stinger configuration that is known has an radius of 150 m, and in addition to that I have all the roller positions relative to the hinge point. I now want to change the stinger radius to 130 m and I want to know the new positions for my rollers. This is maybe more a mathematical question but I hope to get an answer here though
Can you help me?

Regards

It's a geometry question.

BigInch is right, it's more geometry than egineering problem.
Neverthelessk, you didn't specify all the circumstances of changing the stinger radius? Why do you need change the radius, what kind of stinger is it (one segment or articulated?), ... and many others.
Place here some sketch and more data, so then maby someone will help you.
