(instance lever CaseRole) Mid-level-ontology.kif 1616-1616 lever is an instance of case role
(documentation lever EnglishLanguage "(lever ?R ?O) is a CaseRole specifically applied to the %Motion of Rotating. Anything which is actually used as a lever, since many things can be used as such, regardless of the intent during their Manufacture. A lever necessarily has a fulcrum around which the lever exhibits Rotating. It has a mechanicaladvantage at the point of output compared to the point of input of force.")
