Kinematics-Tree

The Kinematics-Tree shows the structure of each kinematic-chain.

KinematicLoop

This is the symbol at the head of the Kinematic-Tree - labelled 'Mechanisms'.

Your objective is to make the Mobility of each kinematic-chain equal to zero. Then, we say the kinematic-chain is a kinematically-defined chain.

In the Kinematics-Tree, the kinematic-chains are either:

A.Solve[d] Mechanisms : Kinematic-chains that are Kinematically-Defined - called 'kinematically-defined chains'.

These kinematic-chains are identified in the Kinematics-Tree with the Green Mobility-fullydefined icon.

You can explore these kinematic-chains in the Kinematics-Tree.

These kinematic-chains are constructed with Dyads, Geared-Rockers, ...

These 'constructions' are themselves constructed with the 'fundamental kinematic elements' : Parts, Joints, Motion-Dimensions...

In the graphic-area, Parts and Joints that are Kinematically-Defined have Green Part-Outlines and Joints.

- or -

B.Unsolved Mechanisms : Kinematic-chains that not Kinematically-Defined .

These kinematic-chains are identified in the Kinematics-Tree with the Blue Mobility-underdefined icon.

You can also explore these kinematic-chains.

You will only see the Fundamental kinematic elements: Parts and Joints.

Kinematic Chains in the Kinematics Tree

An example Kinematics-Tree

Kinematically Defined-Chain is made with:
