Lever is obtained as which is the mechanical advantage of the lever. This equation shows that if the distance "a" from the fulcrum to the point "A" where the input force is applied is greater than the distance "b" from fulcrum to the point "B" where the output force is applied, then the lever amplifies the input force. If the opposite is true that the distance from the fulcrum to the input point "A" is less than from the fulcrum to the output point "B", then the lever reduces the magnitude of the input force. Lever A lever ( or )
Colt Ring Lever rifles Lever rifle began production and continued until 1841, with a total of about 500 manufactured (serial numbers 1 through 500). Because only a small number of the Ring Lever rifles were manufactured, they are considered rare finds among all Colt firearms, with the First Model being the rarest firearm produced under the Patent Arms Manufacturing Company. Although neither the First nor Second Model Ring Lever rifles saw widespread adoption by any military organization, several were procured by the United States Army and the Texas Navy. After an unfavorable review by Army officials in September 1837, which reported that Colt's First
