LinearVelocity — Extraction of linear velocity of point relative to observer [mathematica]

Reference for maple version: Appendix B in Multibody Mechanics and Visualization by Harry Dankowicz, published by Springer Verlag UK, 2004.

Calling Sequence

LinearVelocity[O,P]

Parameters

O: name of defined observer

P: name of defined point

Description

The function LinearVelocity returns the linear velocity of the point P relative to the observer O.

Remember to invoke DeclareStates prior to using LinearVelocity.

Examples

Restart; DeclareObservers[A]; DeclarePoints[A,B]; DeclareTriads[a]; DefineObservers[{A,A,a}]; DefinePoints[{A,B,a,q1,q2,q1-q2}]; DeclareStates[q1,q2]; LinearVelocity[A,B]
