engineering recuitment GATE ME 2023-24 Test Series Mechanical Vibrations Undamped Free Vibration Vibration of Beam and Pendulum
An elastic beam, simply supported at the ends, carries a concentrated mass at the middle of its length. If the natural frequency of the beam neglecting the weight is ωn, considering the weight of the beam the natural frequency of the system will be
1
greater than ωn
2
less than ωn
3
zero
4
equal to ωn, as the natural frequency is independent of concentrated load
