WebIn examinations one of the first questions will probably for you to work out the ' gear ratio ' (sometimes called velocity ratio ). As a guide - always assume that the larger gear revolves one revolution. The number of rotations of the second gear has then to be worked out. In the example below, the DRIVER has 60 teeth and because it is the ... Web1) The size of the force, limited by the strength of the person. 2) The distance between the pivot and where the force is applied, limited only by the length of the lever.
