Links can be classified into binary, ternary and quaternary depending upon their ends on which revolute or turning pairs can be placed. The links shown in fig. 3 are rigid links and there is no relative motion between the joints within the link.

the crank-rocker, in which the input crank fully rotates and the output link rocks back and forth; the slider-crank, in which the input crank rotates and the output slide moves back and forth; drag-link mechanisms, in which the input crank fully rotates and drags the output crank in a fully rotational movement.

A fluid link is deformed by having fluid in a closed vessel and transmitting motion via the fluid via pressure. For example, hydraulic press and hydraulic jack.

TYPES OF LINKS: Links can be classified into Binary, Ternary, and Quaternary etc. depending upon its ends on which revolute or turning pairs can be placed.

A link of mechanism is an assembly of bodies connected to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. Link :- links are connected in such a way that no motion is possible, it results in a locked chain or structure.

§ Rigid: It undergoes no deformation; Example: crank, connecting rod. § Flexible: Partial deformation; Example: springs, belts, ropes. § Fluid: Motion is transmitted by this link by deformation. The two links or elements of a machine, when in contact with each other, are said to form a pair.

Types of Kinematics Link: Rigid Link. Flexible Link. Fluid Link. Floating Link.

Joints: These are links that allow relative motion between two parts of a mechanical system. Joints can be classified as revolute, prismatic, or planar, depending on the type of motion they allow.
