Aerospace Engineering > GATE 2009 > Damped Vibrations
A uniform rigid bar of mass m=1 kg and length L=1 m is pivoted at A. It is supported by a spring of
stiffness k=1 N/m and a viscous damper of damping constant C=1 N-s/m, with shown below. The moment of inertia of the rigid bar is IA=mL2/3
The system is
A
overdamped
B
underdamped with natural frequency ωn=1 rad/s
C
critically damped
D
underdamped with natural frequency ωn=2 rad/s

Correct : c
