- 1. Mechanics of Machinery Naseel Ibnu Azeez Assistant Professor, ME MIT-Anjarakandy naseel@mitkannur.ac.in
- 2. Link Kinematic Pair Linkage Mechanism 4-Bar Mechanism Slider-Crank Mechanism Double Slider-Crank
- 4. Grashof condition The Grashof condition for a four-bar linkage states: If the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighbouring link. In other words, the condition is satisfied if S+L ≤ P+Q where S is the shortest link, L is the longest P and Q are the other links.
- 5. Parallelogram 4-Bar Mechanism First Inversion
- 7. Watt Mechanism The central moving point of the linkage is constrained to travel on an approximation to a straight line. Third Inversion
- 8. Pantographs A pantograph is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. Fourth Inversion
