1. Rayleighs energy method
Rayleighs method is based on the principle of conservation of energy.
The energy in a dynamic system consist
Rigid Body Dynamics
In practice, it is often not possible to idealize a system as a particle. In this section, we construct a more
sophisticated description of the world, in which objects rotate, in addition to translating. This
Modal Analysis (Simulation)
Short Form Report
Section / Group:
This laboratory experience has been designed to demonstrate a number of the properties of
eigenvalue/vector analyses as they are used in the field of vibration.
Modeling Nuclear Motion (Vibrations)
Harmonic Oscillator Ham
must simplify system to "lumped mass"
Use newtonian method: force based
Get an EQUATION OF MOTION (E.O.M.)
*MUST USE A STABLE EQUILIBRIUM POINT*
Static should be based off this equilibrium point
Dynamic should perturb the mass slightly
