Grashof double crank

WebDec 1, 1986 · A Class II linkage is neither a triple-crank nor a double-crank linkage. However, it may be a conditional double-crank, single-crank or zero-crank linkage. The proposed five-bar mobility criterion includes the four-bar Grashof criterion as a special case. Issue Section: Mechanisms Papers Topics: Linkages, Mechanical admittance
