1. A mechanism comprising:
- a mechanical transmission with an input mechanism and an output mechanism; and
wherein a ratio of the motion of the input mechanism to the output mechanism varies continuously such that the effort required to move the output mechanism varies linearly with the motion of the output mechanism and the slope of the effort is a negative constant.

Abstract
A system is presented for counterbalancing the gravitation moment on a link when the link is supported at a point. A first spring mechanism balances the link about all axes that pass through the support point. The link can be balanced throughout a large range of motion.
