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 .
Darcy Lever a newsagent, a general store and four public houses, the Lever Bridge Inn, the Volunteer (formerly the Artillery & Volunteer), the Farmer's Arms and the Lever's Arms. The village also features two cricket pitches and borders both Moses Gate Country Park and Leverhulme Park. Darcy Lever also has the steepest public highway in Bolton, Gorses Steps. Through the village and park run the remains of the Manchester Bolton and Bury Canal and the Bolton-Bury/Radcliffe railway line, which had a station which was open between 1848 and 1951.
