Harmonic excitation refers to a sinusoidal external force of a certain frequency applied to a system. ... Resonance occurs when the external excitation has the same frequency as the natural frequency of the system. It leads to large displacements and can cause a system to exceed its elastic range and fail structurally.
Answer:
There are 2 expected readings greater than 2.70 V
Solution:
As per the question:
Total no. of readings, n = 60 V
Mean of the voltage, 
standard deviation, 
Now, to find the no. of readings greater than 2.70 V, we find:
The probability of the readings less than 2.70 V,
:

Now, from the Probability table of standard normal distribution:

Now,

Now, for the expected no. of readings greater than 2.70 V:

No. of readings expected to be greater than 2.70 V = 
No. of readings expected to be greater than 2.70 V =
≈ 2
