A link is the relative position of one point in a mechanism to another. It can be measured in terms of displacement, distance, or any other appropriate parameter. Links are essential for understanding the kinematic relationships between different parts of a mechanism, including joints, gears, and other mechanical components.
A kinematic pair is a pair of links connected by a joint. The joint specifies the relative motion between the two links, and it determines the types of motion that can occur between them.
Examples of links:
The connecting links between adjacent joints in a machine.
The shaft connecting a crank to the gear.
The link between the two wheels of a bicycle.
Examples of kinematic pairs:
The joint between the piston and piston rod in an engine.
The link between the handle and the wheel of a lever.
The gears in a transmission.
Key points about links and kinematic pairs:
Links determine the relative position of points in a mechanism.
Joints allow multiple links to be connected.
A kinematic pair defines the relative motion between two links.
Different types of links can be connected to create different kinematic pairs
