Which of the following is correct?(a) Wn = \(\sqrt{\frac{k}{m}}\)(b) W

1.	Which of the following is correct?(a) Wn = \(\sqrt{\frac{k}{m}}\)(b) Wn = 1.2\(\sqrt{\frac{k}{m}}\)(c) Wn = 2k(d) Wn = \(\sqrt{\frac{1}{m}}\)The question was asked at a job interview.This question is from Dynamic Stability topic in division Stability, Control, and Handling Qualities of Aircraft Design
Answer» The correct OPTION is (a) WN = \(\sqrt{\FRAC{k}{m}}\) Explanation: A typical RELATION of natural frequency is illustrated in the above question. Natural frequency in the terms of spring COEFFICIENT and mass can be given as follows Wn = \(\sqrt{\frac{k}{m}}\) where, Wn = natural frequency, k is spring coefficient and m is mass of the system.
