Answer following short questions. (i) What are the series of processes involved in the communication process? (ii) Why do we need modulation? Q-2 Answer following multiple choi T A

Answers

Answer 1

The communication process involves a series of steps from the sender encoding the message to the receiver decoding it, with modulation being necessary for efficient signal transmission by optimizing bandwidth utilization, maintaining signal integrity, ensuring compatibility, and enabling long-distance transmission.

(i) The series of processes involved in the communication process include:

Sender: The sender initiates the communication by creating and encoding a message.

Message: The information or content being communicated by the sender.

Encoding: The process of converting the message into a suitable format for transmission.

Channel: The medium through which the encoded message is transmitted, such as a telephone line or radio waves.

Decoding: The process of converting the encoded message back into its original form.

Receiver: The intended recipient of the message who decodes and interprets it.

Feedback: The response or reaction from the receiver, indicating whether the message was understood or not.

(ii) Modulation is needed in communication for efficient transmission of signals over long distances and through different mediums. Modulation is the process of modifying a carrier signal with the information being transmitted. There are several reasons why modulation is necessary:

Bandwidth utilization: Modulation allows multiple signals to be transmitted simultaneously over a single channel, optimizing the use of available bandwidth.

Signal integrity: Modulation helps in overcoming noise and interference during transmission, ensuring that the signal remains intact and can be accurately decoded at the receiver's end.

Compatibility: Different communication systems and devices operate at various frequency ranges. Modulation allows for compatibility between different systems by translating signals into the appropriate frequency range.

Long-distance transmission: Modulation techniques enable signals to travel longer distances without significant degradation. By altering the characteristics of the carrier signal, modulation helps in amplifying and boosting the signal strength.

Explain with words and equations. No number calculation needed. (5 points)

Answers

These methods aim to increase the stiffness and natural frequency of the shaft-gear system, ultimately raising the critical speed at which it operates.

1) The reaction forces for the xy plane and xz plane at the bearings can be determined by applying the principles of static equilibrium. In the xy plane, the reaction force in the y-direction can be determined by summing up the forces in the y-direction and setting it equal to zero. Similarly, in the xz plane, the reaction force in the z-direction can be found by summing up the forces in the z-direction and setting it equal to zero. These calculations involve analyzing the external forces acting on the system, such as applied loads and moments, and considering the geometry and constraints of the bearings.

2) To compare the locations O, A, B, and C and determine the location of maximum total bending moment, one needs to analyze the bending moments at each location. The total bending moment at a given point is the sum of the bending moments caused by applied loads and moments. By calculating the bending moments at each location using the appropriate equations and considering the applied loads, the location with the highest total bending moment can be identified. This could involve using formulas such as the bending moment equation for a beam subjected to point loads, distributed loads, or moments.

3) At the location of maximum total bending moment, the bending stress and torsional shear stress can be determined. Bending stress is calculated using the bending moment and the moment of inertia of the cross-section of the shaft. Torsional shear stress, on the other hand, is determined by dividing the torque applied to the shaft by its polar moment of inertia. By plugging in the values for the maximum bending moment and relevant geometric properties of the shaft, the bending stress and torsional shear stress at the critical location can be calculated.

4) Using the maximum von Mises stress and maximum shear stress, the realized design factor can be determined based on von Mises and maximum shear stress yielding criteria. The von Mises stress criterion states that the maximum von Mises stress in a material should be less than or equal to the yield strength of the material. Similarly, the maximum shear stress criterion states that the maximum shear stress should be less than or equal to the yield strength. By dividing the yield strength of the material by the maximum von Mises stress and maximum shear stress, respectively, the realized design factors for both criteria can be obtained.

5) The magnitude of the total deflection of the shaft at point A can be determined by solving the differential equation governing the deflection of the shaft under applied loads. This involves setting up the differential equation, considering the boundary conditions (e.g., fixed or simply supported ends), and solving for the deflection equation. By substituting the appropriate values and boundary conditions into the deflection equation, the magnitude of the total deflection at point A can be obtained.

6) The torsional wind-up (dθ dL, rad/in) between point A and B can be calculated by considering the torsional deformation of the shaft between these two points. This can be done by analyzing the applied torque, shaft properties (such as torsional stiffness or shear modulus), and the length between the points. The torsional wind-up represents the change in angle per unit length along the shaft.

7) For fatigue analysis, determining the von Mises σa' (alternating stress) and σm' (mean stress) at the critical point is crucial. The von Mises stress combines the effects of both tensile and compressive stresses and can be calculated using the alternating stress and mean stress. The conservative yield check, σa' + σm' ≤ Sy, ensures that the combined effect of alternating and mean stresses does not exceed the yield strength of the material. This criterion accounts for the potential influence of both tensile and compressive stresses on the material's fatigue life. Stress concentration is neglected in this analysis

Answers

Besides hev and ev motor systems themselves what other systems may use high voltage are the air conditioning compressor, auxiliary battery, and water pump.

Why an excessive voltage is used?

High voltages are utilized in transmission structures due to the fact a better voltage implies a decrease modern-day for a given energy of transmission. With a decrease modern-day, much less warmth is generated withinside the transmission traces and so much less electricity is wasted. Furthermore, it has superb environmental benefits.

To come up with a difficult estimate the common rated energy of the water pump is from 250 watts to 1500 watts. The smaller the water pump, much less is the wattage, much less is the energy consumption, subsequently low is the release and head.Usually, an auxiliary deliver is energy delivery that gives an auxiliary voltage. An instance will clean this up. Say you've got got a switching circuit with score of 220VAC enter and 12VDC output. Enclosure air conditioners may be designed to run on AC and DC voltages.

For the electrode in problem 1. 5, what nonfaradaic current will flow (neglecting any transients) when the electrode is subjected to linear sweeps at 0. 02, 1, 20 v/s?

Answers

The values of non faradaic currect for linear sweeps are :

1) V = 0.02V/sec : Non faradic current = 0.4 micro ampere

2) V = 1V/ sec : Non faradic current = 20 micro amperes

3) V = 20V/sec : Non faradic current =  0.4 milliampere

Given,

Scan rate = V = 0.02V/sec

Cd = 20 microfarad / cm²

Here,

Non faradic current = V * Cd

Non faradic current = 0.02 * 20 * \(10^{-6}\)

Non faradic current = 0.4 micro ampere

If,

V = 1V/sec

Non faradic current = 1 * 20 * \(10^{-6}\)

Non faradic current = 20 micro amperes

If ,

V = 20V/sec

Non faradic current = 20 * 20 * \(10^{-6}\)

Non faradic current =  0.4 milliampere

when traveling on multilane roads with dense traffic, it is illegal for vehicles in the right lane to go faster than those in the left lane.

Answers

False. It is forbidden for cars inside the right lane to overtake motorists in the left lane along multilane roads with heavy traffic.

How do multilane roadways work?

Multi-lane roads are those that have more than one lane running in each direction. The majority of multi-lane roadways, such as that shown in this picture, have two lanes in each direction. There may be as many as four vehicles in each heading on some other multi-lane roadways, such expressways and freeways.

When is it safe to operate a vehicle on a highway with many lanes?

While passing or getting ready to make a left turn on even a multi-lane road, you ought to travel in the left lane; when making a right turn or getting ready to enter or exit the road, you ought to travel in the passing lane. Do not pass on the right.

Assignment 1: Structural Design of Rectangular Reinforced Concrete Beams for Bending
Perform structural design of a rectangular reinforced concrete beam for bending. The beam is simply supported and has a span L=20 feet. In addition to its own weight the beam should support a superimposed dead load of 0.50 k/ft and a live load of 0.65 k/ft. Use a beam width of 12 inches. The depth of the beam should satisfy the ACI stipulations for minimum depth and be proportioned for economy. Concrete compressive strength f’c = 4,000 psi and yield stress of reinforcing bars fy = 60,000 psi. Size of stirrups should be chosen based on the size of the reinforcing bars. The beam is neither exposed to weather nor in contact with the ground, meaning it is subjected to interior exposure.
• Use the reference on "Practical Considerations for Rectangular Reinforced Concrete Beams"
• Include references to ACI code – see slides from second class
• Include references to Tables from Appendix A
• Draw a sketch of the reinforced concrete beam showing all dimensions, number and size of rebars, including stirrups.

Answers

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

New cities from scratch are often portrayed as utopian and solutions to the problems of existing cities (pollution, crime, poverty, poor housing, and infrastructure, etc.). This was the case with the 20th Century British New Town movement and it is again the case with new smart and sustainable master planned cities, although the details are very different. How would you assess the promises made about scratch cities and what might be of concern?

Answers

Assessing the promises made about new cities built from scratch requires a critical evaluation of their potential benefits and challenges. While such cities may offer solutions to existing urban problems, there are several factors of concern that need to be considered:

1. Implementation Challenges: Building a city from scratch is a complex and challenging task. It involves extensive planning, coordination, and financial investment. Delays and cost overruns can be common, impacting the realization of promised benefits.

Social Displacement: The creation of new cities may involve displacing existing communities or disrupting established social networks. This raises concerns about the potential marginalization of vulnerable populations and the loss of cultural heritage.

Sustainability and Environmental Impact: While new cities often aim to be sustainable, the actual environmental impact depends on factors such as resource consumption, waste management, and carbon emissions. The ecological footprint of construction, transportation, and ongoing operations must be carefully considered.

Affordability and Accessibility: Ensuring affordable housing, inclusive amenities, and accessible public services in new cities is crucial for addressing social equity. High costs, exclusionary practices, or limited accessibility can lead to socioeconomic disparities and exclusion.

Long-Term Viability: The long-term viability of new cities depends on various factors such as economic diversification, governance structures, citizen engagement, and adaptability to changing social, economic, and environmental conditions. Failure to anticipate and address these challenges can impact the sustainability and success of the new city.

Assessing the promises made about scratch cities requires a comprehensive evaluation of these factors, considering the specific context, governance frameworks, stakeholder engagement, and long-term planning. It is essential to carefully balance the potential benefits with the concerns to ensure the development of successful and inclusive new cities.
