A2 meter long bar has a longitudinal/axial wave speed of 5,000 m/s. if the bar is fixed at each end, what is the second natural frequency an for this system in rad/s? a. 12,450 b. 14,850 e 15,710 d. 16,800 e. 18,780 f. none of the above

The second natural frequency an for this system is 15710 rad/s.

(e) is correct option.

Explanation:

Given that,

Length = 2 m

Wave speed = 5000 m/s

We need to calculate the second natural frequency

Using formula of Time period

We know that,

The frequency is the reciprocal of time period.

We know that,

So, The frequency is in rad/s

Hence, The second natural frequency an for this system is 15710 rad/s.
