The undamped natural frequency of the second-order low pass system may be identified as the frequency at which the phase shift = __________ degrees.
Answer: Phase shift () = [{sqrt(1-^2)}/]
for undamped system, = 0 ; it implies that = [1] = 45 degrees.

2. An undamped mass on a spring has a natural frequency of 10Hz. The system consists of four identical springs in parallel, and suffers some damage so that one spring is removed, and at the same time the mass is halved. Find the modified natural frequency (in Hz) of the system after damage. [5]
2. An undamped spring-mass system with a mass of 1.3kg is observed to have a natural frequency of 90 cycles per second. What is the spring constant?
