  • MECHANICAL VIBRATIONS A70346 IV B.Tech I Semester

    The vibration is started by some input of energy but the vibrations die away with time as the energy is dissipated In each case when the body is moved away from the rest position there is a natural force that tries to return it to its rest position Free or natural vibrations occur in an elastic system when only the internal restoring forces of the system act upon a body Since these forces
