engineering recuitment AAI JE Technical Mock Test 2020-21 Mechanical Vibrations Undamped Free Vibration Mass Pulley System
A disc of mass m is attached to a spring of stiffness k as shown in the figure. The disc rolls without slipping on a horizontal surface. The natural frequency of vibration of the system is
1
\(\frac{1}{{2\pi }}\sqrt {\frac{k}{m}}\)
2
\(\frac{1}{{2\pi }}\sqrt {\frac{{2k}}{m}}\)
3
\(\frac{1}{{2\pi }}\sqrt {\frac{{2k}}{{3m}}}\)
4
\(\frac{1}{{2\pi }}\sqrt {\frac{{3k}}{{2m}}} \)
