WebJul 9, 2024 · Explanation: According to Grashof’s Law: "A four-bar mechanism has at least one revolving link if the sum of the lengths of the largest and shortes ... Such a link is known as a crank or driver i.e. AD (link 4 ) is a crank. The link BC (link 2) ... Double Crank Mechanism; If any of the adjacent links of the shortest link if fixed: Crank ... WebThe gross classification of a mechanism is Grashof (having a fully rotatable link) or non-Grashof and then it is further cate-gorized with the familiar titles of crank-rocker, Grashof double-rocker, drag link and the likes. Proofs of the Grashof criterion can be found in Williams and Reinholtz (1986), Paul (1979),
