can someone tell me the exact definition of kinematic pairs?and kinematic chain?
which is the one where relative motion is constrained?
which is the one where relative motion is constrained?

In summary, a kinematic pair is a connection between two rigid bodies that allows for relative motion, while a kinematic chain is a series of connected kinematic pairs that create a mechanism or system capable of performing a specific task. There are four types of kinematic pairs: revolute, prismatic, cylindrical, and spherical, each allowing for different types of motion. These pairs and chains have various applications in engineering, robotics, and biomechanics and can be analyzed using principles of kinematics, such as mathematical equations, graphical analysis, or computer simulations.

Hi monty37! 
A pair is 2, and a chain is more than 2 …
see http://en.wikipedia.org/wiki/Kinematic_pair and http://en.wikipedia.org/wiki/Kinematic_chain …
but they're all constrained.

Kinematic pairs are defined as two connected elements in a mechanism that allow relative motion between them. They are typically composed of a moving element, known as the driver, and a stationary element, known as the follower. This type of connection is essential in understanding the motion and behavior of mechanical systems.
A kinematic chain, on the other hand, refers to a series of interconnected kinematic pairs that form a continuous motion path. This allows for complex movements and transformations within a mechanism.
The kinematic pair that constrains relative motion is known as a constrained pair. It restricts the motion of one element with respect to the other, allowing for controlled and precise movement.
Understanding the concepts of kinematic pairs and chains is crucial in the field of mechanical engineering, as it helps in designing and analyzing mechanisms for various applications.
1. What is a kinematic pair?
A kinematic pair is a connection between two rigid bodies that allows for relative motion between them. This can include sliding, rolling, or spinning motions.
2. What is a kinematic chain?
A kinematic chain is a series of connected kinematic pairs that create a mechanism or system capable of performing a specific task. This can include simple machines, such as gears and levers, or more complex systems, such as robots.
3. What are the types of kinematic pairs?
There are four types of kinematic pairs: revolute, prismatic, cylindrical, and spherical. Revolute pairs allow for rotary motion, prismatic pairs allow for linear motion, cylindrical pairs combine rotary and linear motion, and spherical pairs allow for motion in all directions.
4. What are the applications of kinematic pairs and chains?
Kinematic pairs and chains have various applications in engineering, robotics, and biomechanics. They are used in the design of machines, vehicles, prosthetics, and other mechanical systems to create specific movements and functions.
5. How are kinematic pairs and chains analyzed?
Kinematic pairs and chains are analyzed using principles of kinematics, which involves studying the motion of objects without considering the forces that cause the motion. This can be done through mathematical equations, graphical analysis, or computer simulations.
