Question

Chain and link relative motion explanation

Answer 1

In a planar mechanisms, all of the relative motions of the rigid bodies are in one plane or in parallel ... of links and pairs without a fixed link is not a mechanism but a kinematic chain.

hope it helps!!

Answer 2

HEY.

1. Definitions of kinematics links, pairs, chains & Mechanisms.

2. Classifications of kinematics links, pairs, chains & Mechanisms.

3. Diagrams of kinematics links, pairs, chains & Mechanisms

4 Advantages & Disadvantages of kinematics links, Pairs, chains & Mechanisms.

5. Applications of kinematics link, Pairs, chains & Mechanism

6. Examples of kinematics link, Pairs, chains & Mechanisms.

KINEMATIC LINK: – A mechanism is made of a number of resistant bodies out of which some may have motions relative to the others. A resistant body or a group of resistant bodies with rigid connections preventing their relative movement is known as a link. A link also known as kinematic link or element.

Examples :- A slider-crank mechanism consists of four links: frame and guides, crank connecting rod and slider, the crank link may have crankshaft and flywheel also, forming one link having no relative motion of these.

CLASSIFICATIONS OF LINKS:-

1. Binary link

2. Ternary link

3. Quarternary link
