In reply to Connor Nunns:
> This should be true for normal cams, but for totems there might actually be a difference. This is because the lobes don't follow the standard logarithmic spiral shape seen in other cam designs. However I'm not sure how the maths actually works.
I have A levels in maths , further maths and physics, and a degree in civil engineering and can just about handle the maths for an slcd in a straight pull in a parallel crack. If the pull is to one side, it gets complicated, even more so with double axles or totems.
