# On transformations and graphic methods of algebraically 3 dimensional force, velocity and displacement systems

@article{Baranyai2019OnTA, title={On transformations and graphic methods of algebraically 3 dimensional force, velocity and displacement systems}, author={Tam{\'a}s Baranyai}, journal={arXiv: Classical Physics}, year={2019} }

In engineering practice one often encounters planar problems, where the corresponding vector space of forces, velocities or (infinitesimal) displacements is three dimensional. This paper shows how these spaces can be factorized, such that the arising equivalence classes correspond to points and lines of action of the forces / velocities / displacements in the (projective) plane. It is shown how the study of projective transformations and dualities of planar mechanical systems is closely related…
