Lever the power out, and the ratio of output to input force is given by the ratio of the distances from the fulcrum to the points of application of these forces. This is known as the "law of the lever." The mechanical advantage of a lever can be determined by considering the balance of moments or torque, "T", about the fulcrum. where F is the input force to the lever and F is the output force. The distances "a" and "b" are the perpendicular distances between the forces and the fulcrum. Since the moments of torque must be balanced, formula_3 .
Great Lever II listed mill in 2016 and build new houses, but permission is still needed from the government to knock down the mill because of its listed status. Currently the mill is empty and deemed an eyesore by local residents. Great Lever has a park on Green Lane, on the opposite side of Green Lane from the park are the grounds of Bolton Cricket Club.
