How do you find the ideal mechanical advantage of a can opener?

The ideal mechanical advantage (IMA) of a can opener can be determined by measuring the distances involved in its operation. Specifically, IMA is calculated by dividing the input distance (the distance the handle moves) by the output distance (the distance the can lid is lifted). For example, if the handle moves 10 cm and the lid moves 1 cm, the IMA would be 10. This value indicates the theoretical efficiency of the can opener in amplifying force.
