D Alembert's principle is:
- Alembert’s principle, also known as the Lagrange–d'Alembert principle, is a statement of the fundamental classical laws of motion.
- It is named after its discoverer, the French physicist and mathematician Jean le Ronda d'Alembert.
- D′Alembert’s principle state that “The system of forces acting on a body in motion and the Inertia force of the body is in dynamic equilibrium”.
- i is the integral used for the identification of variable corresponding to the particular particle in the system.
- F i is the total applied force on the ith place.
- m i is the mass of the ith particles.
- a i is the acceleration of ith particles.
- m i a i is the time derivative representation.
