To determine the minimum bit rate of an ADC (Analog-to-Digital Converter) with a 1000-level quantizer and a bandwidth of 20 kHz, the minimum bit rate from this ADC is 400 kHz.

In this case, the signal has a bandwidth of 20 kHz, so the minimum sampling rate required is 2 times the bandwidth, which is 2 * 20 kHz = 40 kHz. The minimum sampling rate corresponds to the minimum bit rate.

To convert an analogue signal with a 20 kHz bandwidth to a binary format using a 1000-level quantizer, each level of the quantizer requires a certain number of bits. Since there are 1000 levels, we need at least log2(1000) bits to represent each level. Rounded up to the nearest integer, log2(1000) is 10.

Therefore, the minimum bit rate of the ADC is the product of the minimum sampling rate and the number of bits per sample:

Minimum bit rate = Minimum sampling rate * Number of bits per sample

                = 40 kHz * 10 bits

                = 400 kHz

Hence, the minimum bit rate from this ADC is 400 kHz.

Hello! In this question, we are trying to find the maximum value of shear flow in the web of the wing spar. Note that we are trying to find this with a section that is 1 meter away from the free end of the beam.
__________________________________________________________

Explanation:

In this problem, we know that:

This information should be kept in mind and can help us solve our problem.

__________________________________________________________

Solve:

Let us begin to solve the problem.

Since we're analyzing the moment in one section, in this case, we can note this as "section 1", we can use this formula to determine the moment in this section:

\(M_{1}=\frac{wl^2}2}\)
Whereas:

Plug in the values into the equation and solve:

\(M_{1}=\frac{15*1^2}2}=7.5\text{kN-m}\)
Now, let us find the moment of inertia of the beam in our 1st section. We'll use the formula:

\(I_{xx}=\frac{BD^3}{12} +2Ah^2\)

Whereas:

Plug in the values into the equation and solve:

\(I_{xx}=\frac{2(300)^3}{12} +2(500)(150)^2=2.7\times10^7\:\text{mm}^4\)
Now knowing our moment and inertia, we can solve our direct distress in the z direction of our flanges using the following formula:

\(\sigma_{z,U} = -\sigma_{z,L}=\frac{M_{1}}{I_{xx}}y\)
We know:

Plug the values into the equation and solve. (Note that unit conversion was done for M1):

\(\sigma_{z,U} = -\sigma_{z,L}=\frac{7.5\text{kN-m}*(\frac{1000 N}{1kN})(\frac{1000mm}{1m} )}{2.7\times10^7}(150mm)=-41.7\:\text{N/mm}^2\)
Since we now know what our direct distress is, we can find the bending moment resultant with the formula:

\(P_{z,U}=\sigma_{z,U}\times A\)

We know:

Plug in the values to our equation and solve:

\(P_{z,U}=-41.7\:\text{N/mm}^2\times 500\:mm^2=-20850\:N\)
Now knowing our bending moment resultant, we can now find our flange load of the web section. Note that our flange load is uniformly distributed. We will use the formula:

\(P_{U}=\sqrt{P_{z,U}^2+P_{y,U}^2}}\)
We know that:

Plug in the values into the equation and solve:
\(P_{U}=\sqrt{(-20850)^2+0^2}}=20850\:N\)
Please note that the answer we calculated above is our tension (T).

Let's now calculate our bending moment resultant using:

\(P_{y,L}=P_{z,L}\times\frac{\delta{y}^2}{\delta_{z}}\)

We know:

Plug in the values and solve. To make things go faster, I included the unit conversion for our denominator value:

\(P_{y,L}=-20850\:N\times\frac{100\:mm}{(1\:m\times\frac{1000\:mm}{1\:m} )}=-2085\:kN=2085\:kN\)
Please note that the above calculation would be our compression value.

Let's calculate our shear force in the web in our 1st section using a known relationship:

\(S_{y}=-W\times\delta_{z}+P_{y,L}\)
We know:

Plug in our known values and solve:

\(S_{y}=-15\times(1\:m\times\frac{1000\:mm}{1\:m} )+2085=-12915\:N\)

In order to figure out what our shear flow is (note that our shear flow is represented as q), we will use the relationship:

\(q=\frac{S_y}{I_{xx}} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)

We know:

Plugging in the values, we will get:

\(q=\frac{12915}{2.7\times10^7\:mm} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)

Simplify the equation:

\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\)
Integrate the equation:

\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\\\\q=4.78\times10^{-4} ((300s-\frac{2s^2}{2} +[0])+75000)\\\\q=4.78\times10^{-4} ((300s-s^2 )+75000)\)

We now have our equation for the shear flow. We know that the max value of shear flow will happen when s equals 150 mm, so let's plug in the value 150 mm into "s" in our "q" equation and solve:

\(q=4.78\times10^{-4} ((300(150)-150^2 )+75000)=\boxed{46.8\:N/mm}\)

__________________________________________________________

Answer:

The max value of shear flow in the web in the 1st section of the beam is:

\(q=\boxed{46.8\:N/mm}\)

About 1 MW is released each day when 1 g of uranium or plutonium fissions. This is roughly equivalent to 3 tons of coal or 600 gallons of fuel oil burned each day, which releases about 1/4 tonne of carbon dioxide when burned. (One metric ton, or tonne, is equal to 1000 kg.)

The total binding energy released during the fission of an atomic nucleus varies depending on the exact breakdown but typically ranges between 200 MeV* and 3.2 x 10-11 joules for U-235. About 82 TJ/kg is this.

In actuality, burning 3 tons of coal produces the same amount of energy as fissioning 1 gram of uranium 235 (1)! It is possible to use the energy generated by the fission of uranium or plutonium to generate electricity, launch spacecraft, and power weapons like the atomic bomb.

Answer:

a. Commutator:

the commutator reverses the current direction with each turn serving as a mechanical rectifier to convert the alternating current from the windings to unidirectional direct current in the external load circuit.

b. Armature core

Armature core is a physical structure made up of silicon steel stampings. The core is laminated to keep iron losses low. Armature winding is the main current carrying winding where we either provide(electric supply to motor) or extract e.m.f(collect electric power from generator).

c. Field system

The field winding basically form an electromagnet, that produces field flux within which the rotor armature of the DC motor rotates, and results in the effective flux cutting

d. Brushes

The function of brushes is that the brushes conduct current between stationary wires and moving parts of the electric Generator.

e. Armature winding

The winding wound on the core is given current through a DC supply. This current-carrying winding as under the influence of the magnetic field develops a force that develops a rotational torque. This torque enables the machine to rotate.

Explanation:

Answer:

A. Yes, it will run

B. X will not replace any value

Explanation:

A. Will it run?

First, the algorithm can be interpreted in python as follows:

#Set Minimum to 1

MINIMUM = 1

#For every element X in the list L

for X in L:

#If current element X is less than MINIMUM

    if X < MINIMUM:

#Set MINIMUM to X

         MINIMUM = X

#Print MINIMUM

print(MINIMUM)

The algorithm will run without error because it follows the right sequence and has no syntax error

B. Will X replace any value?

No, it won't

The smallest positive integer is 1.

So, setting the MINIMUM to 1 means that the value of X in the list will not replace the MINIMUM because the MINIMUM has already been set

The sampling technique used in this data collection is stratified random sampling.

Explanation:
Stratified random sampling is a sampling technique where the population is divided into strata or subgroups based on specific characteristics, and then a random sample is selected from each stratum. In this example, the civil engineering student has divided the population of drivers into three classes, and plans to select a random sample from each class. This ensures that the sample is representative of the entire population and reduces the chance of bias in the data collection process.

Stratified random sampling is a useful technique when there is a significant difference in the characteristics of different subgroups within the population. By dividing the population into strata, the sampling process can be more targeted and precise, and the resulting data can provide more accurate insights into the population as a whole.

Overall, using stratified random sampling in this data collection process is a wise choice as it will help the civil engineering student gather accurate and representative data for his thesis.
