The input to a harmonic generator is a periodic waveform v(t) = Ce^-alpha t, 0 < t < 1, T = 1 with alpha < 0. The outpu
t is to be derived through a filter which will pass only one frequency. If alpha can be adjusted, what value of alpha will give the maximum output through the filter for the second harmonic the third harmonic? the fifth harmonic?

Answer:
Explanation:
Given that:
The Inside pressure (p) = 1402 kPa
= 1.402 × 10³ Pa
Force (F) = 13 kN
= 13 × 10³ N
Thickness (t) = 18 mm
= 18 × 10⁻³ m
Radius (r) = 306 mm
= 306 × 10⁻³ m
Suppose we choose the tensile stress to be (+ve) and the compressive stress to be (-ve)
Then;
the state of the plane stress can be expressed as follows:
Since d = 2r
Then:
When we take a look at the surface of the circular cylinder parabolic variation, the shear stress is zero.
Thus;
Answer:
And we can find this probability with this difference:
And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
Explanation:
For this case we can define the random variable X as "hours that a person watches television". For this case we don't have the distribution for X but we have the following parameters:
We can assume that the distribution for X is normal
And we want to find this probability:
And we can use the z score formula given by:
And we can find the z score for each limit and we got:
And we can find this probability with this difference:
And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
