Dynamic system is a combination of matter whose parts are capable of making relative movements. Any system with mass and elasticity capable of vibrating motion. The mass is the constitution of the system, and the elasticity is due to the possibility of relative movement of the parties constituting this mass. Vibrations are evident everywhere, a vibrational movement is triggered when the system is moved from its equilibrium position due to energy transmitted to the system via an external source. This course is intended for core core students in the Science and Technology field and more particularly to 2nd year undergraduate students in the Civil Engineering sector and G.P.
