Linkage Design (I)6 The function of a mechanism in a machine is to convert the input force ormotion into desired output. In a linearly proportional mechanism, the output motion or force is linearlyproportional to the input. In some mechanisms, the relation between output and input is nonlinear. Thenumber, type and connectivity of joints, and the length of links determine thecharacteristic of the mechanism. Such mechanism is called a linkage. The purpose of linkage design is to decide the length of the links, the positionand type of the joints, and how to assemble the links so that the e desired motioncan be achieved.
Linkage Design (II)7 When analyzing a linkage, we often use a “skeleton diagram” to represent thetype of joints, distances between joints, and which joints connect which links inthe linkage
