Regarding the importance of masses movement in space and their contact with each other, it is felt that in order to design and optimize dynamic systems (dynamic mechanics), a reasonable relation should be established between their subsets. This paper attempts to prove such a relation in the simplest possible way.</p>}, number={5}, journal={JOURNAL OF ADVANCES IN MATHEMATICS}, author={Mahbod, Mohammad}, year={2015}, month={May}, pages={3463–3471} }
