RELATIVE VELOCITY
Even though the earth is continuously moving velocities are measured relative to it.
The earth is regarded as fixed.
Similarly a moving point A may be regarded as fixed and the velocity of any other
point B measured relative to the point

Balancing Masses in Same Plane
Components that are to be used in high rotational
speeds should have their centers of mass
coinciding with the geometrical center to avoid
outbalance forces acting on them.

FREE DAMPED VIBRATION
When a body is subjected to damping Force, this may be due to:
1. Viscous Friction in which the resistance is assumed to be proportional to the
velocity.
2. Coulomb friction for dry surfaces in which the resistance is assumed to be
