Exercise 6.4
[0.857[Hz]]
In the linkage shown below, the bars AB and CD are uniform in section and
each has a mass of 1.2[kg],whilethediscatD,carriedbyth(e)/(b)ar CD,is150
[mm] in diameter and has a mass of 1 [kg].
The mass of link BE is 1 [kg], the spring has a mass of 1.5 [kg] and a
stiffness of 400[(N)/(m)].
Find the natural frequency of vibration of the system for small oscillations.
