Question
A uniform thin disk of mass 1 kg and radius 0.1 m is kept on a surface as shown in the figure. A
spring of stiffness k1
400 N/m is connected to the disk center A and another spring of stiffness
k2
= 100 N/m is connected at point B just above point A on the circumference of the disk.
Initially, both the springs are unstretched. Assume pure rolling of the disk. For small disturbance
from the equilibrium, the natural frequency of vibration of the system is
off to one decimal place).
