There are four main elements that join pairs in mechanics: force, motion, energy, and power. Each one of these elements has a specific purpose and function.
Force is the element that allows two objects to push or pull on each other. It is the force that makes it possible for two objects to interact with each other.
Motion is the element that allows two objects to move relative to each other. It is the motion that makes it possible for two objects to change their position or direction.
Energy is the element that allows two objects to exchange energy. It is the energy that makes it possible for two objects to interact with each other.
Power is the element that allows two objects to generate power. It is the power that makes it possible for two objects to interact with each other.

Q: What are pairs in mechanical engineering?
A: Pairs are two equal and opposite forces that act on two different objects.
Q: What are types of pair?
A: There are many different types of pairs, including:
-Matching pairs: these are pairs where both items are the same, such as a pair of socks
-Complementary pairs: these are pairs where the two items go together, such as a pair of shoes
-Contrasting pairs: these are pairs where the two items are different, such as a pair of black and white socks
-Asymmetrical pairs: these are pairs where the two items are not the same, such as a pair of earrings
Q: When two elements in a pair when they are in motion it is referred to as a lower pair?
A: No, when two elements in a pair are in motion it is referred to as a “dynamic pair.”
Q: How are pair classified?
A: Pairs can be classified in a number of ways, including by their type (e.g. perfect, semiperfect, or imperfect), by their structure (e.g. as a complete, incomplete, or unordered pair), or by their content (e.g. as a self-pair or a hetero-pair).
