Single degree of freedom systems
Mass m on frictionless wheels, connected by a spring of
stiffness k to fixed wall also a damper of value c.
The mass is subjected to a force F(t).
The displacement of the mass is x which is a function of t.
The equation of motion of the mass is given by,

Where is the excitation frequency.
You will observe the damping is dependent upon the
velocity of the mass.
Express this equation as,
