Free vibration of fixed beam
A rod 20 mm diameters and 1.2 m long is fixed at both ends and has a mass of 2kg concentrated at the middle. Ignoring the weight of the rod, calculate the frequency of transverse vibrations. Take E=200 Gpa.?
What is the natural frequency in rad/s of a system whose damped natural frequency is 30rad/s and damping ratio is 0.6 ?
The amplitude of a damped system will not change with time.
For an over damped system
The magnification factor is the ratio of maximum amplitude and static deflection.
