Lever a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. Assuming the lever does not dissipate or store energy, the power into the lever must equal the power out of the lever. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot. Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity. If "a" and "b" are distances from the
Darcy Lever at Darcy Lever. Darcy Lever had little industry other than the coal mining. Many inhabitants not involved in coal mining found employment on the Manchester Bolton and Bury Canal or in the textile mills of Bolton and Farnworth.
