Single DOF mass-spring damper

[amh]

1. Under forced vibration

The idealized model can be shown as;



Free body diagram;

mass = mass of the system in kg
c = damping of system in Newton second per meter (Ns/m)
k = stiffness in Newton per meter (N/m)
x = displacement in meter (m)
f = force in Newton (N)
