Yes, a kinematic chain can be either open or closed. An open kinematic chain has one or more free ends, while a closed kinematic chain forms a complete loop with no free ends. Machines often use both types in various configurations. 5. How is the degree of freedom determined in a kinematic chain? The degree of freedom in a kinematic chain is ...

Kinematic chain is an assembly of link in which the relative motion of the links is possible and the motion of each relative to the other is definite. A linkage is obtained if one of the link of kinematic chain is fixed to the ground. If motion of any of the movable links results in definite motions of the others,the linkage is known as mechanism.

Open-chain kinetic exercises, sometimes referred to as isolated movements, occur when the ends of the chain (i.e., the limbs that are doing the movement) are not rooted to the ground. Examples of open-chain kinetic exercises are biceps curls, triceps extensions, lateral raises, knee extensions, hamstring curls, or donkey kicks.

The kinetic link principle, or kinetic chain, describes a chain of events linking body segments to one another and the movement (or lack thereof) of a given body segment affects the segments both proximal and distal to it. 2 This concept is most familiar to us when it comes to lack of motion at a given joint. Whether from an arthritic process ...

Section snippets Kinematic chain diagram. To analyze the machine it is very useful to make a kinematic diagram of the machine. From this kinematic (chain) diagram two groups of axes can immediately be distinguished: the workpiece carrying axes and the tool carrying axes.
