DAlemberts Principle

D'Alembert's Principle, in dynamics of systems of particles, is that the external forces on any system are equivalent to the mass-accelerations produced, the internal forces of the system being in that connection negligible. It is, in fact, a statement that the observed external causes are equivalent, as a whole, to the observed effects produced. By its use generalised methods for solution of innumerable problems are obtained.

“Now faith is being sure of what we hope for and certain of what we do not see.”
Hebrews 11:1
