1st EXAM NI PART Flashcards
Any oscillatory motion.
Vibration
The maximum displacement from the equilibrium position.
Amplitude
Number of oscillations per unit time, measured in Hertz (Hz).
Frequency
The frequency at which a system naturally oscillates when disturbed.
Natural Frequency
A phenomenon where the frequency of external forces matches the natural frequency.
Resonance
A simplified model with one independent motion.
Single Degree of Freedom (SDOF)
The mass that accounts for the inertia of the vibrating body.
Effective Mass
The combined stiffness of the system components
Effective Stiffness
Algebraic equations having identical solutions.
Equivalent Equations
The values that satisfy the equations.
Roots/Solutions
Reducing equations while maintaining equivalence.
Simplification
Calculations of total demand on systems based on metrics like water meter size.
Equivalent Users
Sum of system demands.
Equivalent Load
Drugs producing similar therapeutic outcomes.
Therapeutic Equivalent
Replacement of complex damping mechanisms with simpler models.
Equivalent Viscous Damping
Measure of damping relative to critical damping.
Damping Ratio
Parameter representing energy loss in the system.
Dissipation Constant
Solve For Natural Frequency
Wn = sqrt(k/m)
Solve For Damping Coefficient
c = 2 sqrt(km)
Solve for Logarithmic Decrement
S = 2pi Zeta/sqrt(1- Zeta)
