When a jet aircraft enters a turn or straightens-up from a turn, what device ensures correct response?A) Dorsal fin.B) Yaw damper.C) Aileron - rudder coupling.D) Vortex generators.
Answers
When a jet aircraft enters a turn or straightens up from a turn, the device that ensures correct response is Yaw damper.
So, the correct answer is B.
What's yaw damper?The yaw damper is a system that detects any unwanted yaw motion, or side-to-side movement, and applies corrective control inputs to the rudder. This helps to stabilize the aircraft and maintain a smooth and controlled flight.
A dorsal fin is a vertical stabilizer located on top of the aircraft that helps to reduce turbulence and improve directional stability.
Aileron-rudder coupling is a technique that involves linking the ailerons and rudder to work together during turns, but it is not a device.
Vortex generators are small fins or devices that are placed on the wings of the aircraft to control airflow and prevent turbulent flow. However, they do not directly ensure correct response during turns or straightening-up.
Hence, the correct answer for this question is B.

A 6-cm-diameter horizontal water jet having a velocity of 25 m/s strikes a vertical stationary
flat plate. The water splatters in all directions in the plane of the plate. ANALYZE the linear
momentum equation for a fixed control volume to find; the amount of force required to hold
the plate against the water stream? Take the density of water to be 1000 kg/m3
Answers
In this case, the control volume is the plate and the water jet is the system that is interacting with the plate. The density of water is given as 1000 kg/m3. The velocity of the water jet is 25 m/s and the diameter of the jet is 6 cm, which is equivalent to 0.06 m. The mass flow rate of the water jet can be calculated as follows:
Mass flow rate = Density * Velocity * Area
= 1000 kg/m^3 * 25 m/s * (3.14 * (0.06/2)^2)
= 0.11 kg/s
The momentum of the water jet is equal to the mass flow rate multiplied by the velocity of the jet. The force required to hold the plate against the water stream is equal to the rate of change of momentum of the jet.
Force = Rate of change of momentum
= Mass flow rate * Velocity
= 0.11 kg/s * 25 m/s
= 2.75 N

Why does some core analysis reports show depths broken into 1/2 feet and some in whole feet?
Answers
Answer:
Core analysis reports often show depths broken into increments of 1/2 feet because it provides a more detailed and accurate representation of the geologic layers present in the subsurface. By breaking the depth into smaller increments, geologists can more accurately depict the thickness and distribution of different geologic units and identify any changes or variations within those units. This can be especially important in cases where the geology is complex or there are small variations in the subsurface that could have significant impacts on the exploration or development of a resource.
In some cases, core analysis reports may show depths in whole feet rather than 1/2 feet. This is usually done when the geology is relatively simple and there are no significant variations within the geologic units being analyzed. In these cases, showing the depths in whole feet may be sufficient to accurately represent the geology and meet the needs of the project.
Ultimately, the decision to show depths in 1/2 feet or whole feet will depend on the specific needs of the project and the complexity of the geology being analyzed. Both approaches can be useful for different purposes and it is important to choose the one that is most appropriate for the task at hand.

c. economic value added.
Economic value added is a profitability measure that takes into account both the dollar value of a firm's return and its opportunity costs, and calculates the excess return that the firm generates above and beyond what it would earn by investing in alternative opportunities.
EVA is calculated by deducting the company's total capital costs from its net operating profit after taxes (NOPAT). The formula for calculating EVA is as follows:
EVA = NOPAT - (Capital * Cost of Capital), where
NOPAT represents the company's net operating profit after taxes, which is the profit generated by its core operations.
Capital refers to the total amount of capital invested in the company, including both equity and debt.
Cost of Capital is the weighted average cost of the company's capital, which takes into account the cost of equity and the cost of debt.
By subtracting the capital costs from the company's profits, EVA measures the surplus return generated above the required return on invested capital. A positive EVA indicates that the company is creating value for its shareholders, while a negative EVA suggests that the company is not generating returns that exceed the cost of capital.
EVA is considered a valuable metric because it aligns with the goal of maximizing shareholder wealth. It provides insights into how efficiently a company utilizes its capital and helps assess whether management decisions are generating value. By focusing on EVA, companies aim to improve their financial performance and increase shareholder value over time.

Due to the limitations of online guessing, most password attacks today use ____.
a) offline cracking b) hash replay c) token replay d) online cracking
Answers
A. Due to the limitations of online guessing, most password attacks today use offline cracking.
Online cracking involves an attacker attempting to guess a password by sending login requests directly to a server or application over the Internet. This method can be easily detected and prevented by security measures such as account lockouts and CAPTCHAs. Offline cracking, on the other hand, involves an attacker stealing a password hash or database and attempting to crack the password offline using a powerful computer or specialized software. This method can be more effective than online cracking because the attacker has more time and computing resources to crack the password. To prevent offline cracking, it is important to use strong password hashing algorithms and to store password hashes securely, such as in a separate database or using salted hashes. Additionally, using two-factor authentication or multi-factor authentication can help to further protect against password attacks.

what is the power output of a „U reactor if it takes 30 days to use up 2kg of
fuel Given that energy release per fission is 200MeV and Avogadro's number = 6,023 x 10°
per kilomole
Answers
Answer:
The power output of the reactor is approximately 63.387 MW
Explanation:
The energy released per one fission reaction = 200 MeV
The Avogadro's number, \(N_A\) = 6.023 × 10²³
The mass of fuel used = 2 kg
The mass of one mole of uranium 235, U²³⁵ = 235 grams = 0.235 kg
Therefore, the number of moles of U²³⁵ in 2 kg = 2 kg·mol⁻¹/(0.235 kg) = 400/47 moles ≈ 8.51 moles
The number of uranium atoms in 400/47 moles of U²³⁵ = (400/47) × 6.023 × 10²³ ≈ 5.126 × 10²⁴ atoms of U²³⁵
The energy released per fission of an atom = 200 MeV = 200 × 10⁶ eV × 1.602177 × 10⁻¹⁹ J/(eV) ≈ 3.204354 × 10⁻¹¹ J
The energy, 'E', released by the 5.126 × 10²⁴ atoms of U²³⁵ in the 2 kg of U²³⁵ is given as follows;
E = 3.204354 × 10⁻¹¹ J/atom × 5.126 × 10²⁴ atoms = 1.643 × 10¹⁴ Joules
The power, P = Energy/Time
The time = 30 days = 30 × 24 × 60 × 60 = 2,592,000 seconds
∴ P = (1.643 × 10¹⁴ Joules)/(2,592,000 s) = 63.3873457 megawatts ≈ 63.387 MW
The power output of the reactor, P ≈ 63.387 MW

The unit shear along the south shear walls is 450 lb/ft.
What is the shear capacity along the south shear walls?The unit shear along the south shear walls of the warehouse one-story building is 450 lb/ft in the east-west direction. Unit shear refers to the shear force per unit length, in this case, per foot, acting on the shear walls. Shear walls play a crucial role in resisting lateral forces and maintaining the structural stability of a building.
In this context, the calculated unit shear of 450 lb/ft indicates the maximum shear force that each foot of the south shear walls can withstand without experiencing excessive deformation or failure. It is important to ensure that the shear walls are designed and constructed to withstand these shear forces adequately.
The adequate anchorage of the roof diaphragm to the shear wall is another important aspect mentioned in the question. Proper anchoring ensures a strong connection between the roof diaphragm and the shear wall, allowing the transfer of shear forces effectively and enhancing the overall structural performance.
By calculating the unit shear, engineers and designers can assess the capacity of the south shear walls to resist the applied forces and ensure the stability and safety of the warehouse building.

The steel shaft has a diameter of 40 mm and is fixed at its ends A and B . If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa.
Q6/
Answers
Answer:
See explanation.
Explanation:
Since no figure was given I solved a problem that was similar to the one you described that I worked in my mechanics of materials class. The method should be very similar for your figure. See attached image for my work.
If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.
What we need to perform?We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,
P=2×pi×N×T/60 or T=60×p/2×pi×N
Where P=power transmitted by the shaft=50×10³W
N=rotation speed of the shaft in rpm=730rpm
Pi=3.142
T is the twisting moment
By substituting the values for pi, N and P, we get
T=654Nm or 654×10³Nmm
Also, T=pi×rho×d³/16 or rho=16×T/pi×d³
Where rho=maximum shear stress
T = twisting moment=654×10³Nmm
d= diameter of shaft= 40mm
By substituting T, pi and d
Rho=52Mpa
b. For a hollow shaft, the value for rho is unknown
T=pi×rho(do⁴-di⁴/do)/16
Rho=T×16×do/pi×(do⁴-di⁴)
Where
T= twisting moment=654×10³Nmm gotten above
do=outside shaft diawter=40mm
di= inside shaft diameter =30mm
Pi=3.142
Substituting values for pi, do, di and T.
Rho=76Mpa
Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

consider a stokes flow due to a sphere rotating near a wall, argue from kinematic reversibility weather or not the rotating sphere will experience a force pushing it away or drawing it into the wall
Answers
In Stokes flow, the fluid velocity is proportional to the forces acting on the fluid and the fluid is assumed to be viscous and incompressible. The fluid velocity near a rotating sphere in Stokes flow can be determined using the equations of fluid dynamics.
What is the reversibility about?Kinematic reversibility is a property of Stokes flow, which states that the fluid flow is symmetric with respect to time reversal. This means that if the fluid velocity is recorded at a certain time, then the same velocity field will be obtained if time is reversed and the flow is replayed in the reverse direction.
When a sphere is rotating near a wall, the flow of fluid around the sphere creates a velocity field that pushes the sphere away from the wall. This flow can be considered as the fluid being pushed away from the sphere and towards the wall. If the flow is time-reversed, the fluid velocity field would be the same, but the direction of the velocity would be reversed. This means that the fluid would be drawn towards the sphere and away from the wall, pulling the sphere towards the wall.
Therefore, based on the property of kinematic reversibility in Stokes flow, the rotating sphere near a wall will experience a force that could either push it away from the wall or draw it towards the wall, depending on the direction of the flow.

Production machines often lock out the operator while processing parts plus a fixed time for the machine to come to a stop.
A TOF timer locks the machine doors at the start of the process and lights a door locked indicator. When the part is finished, the TOF timer keeps the doors locked for an additional 5 seconds for the machine to stop.The process of a machine tool working on a part without any human intervention is known as machining automation. This procedure frequently necessitates machine guarding and automation safety devices. In order to increase safety, manufacturing machines are usually equipped with sensors, lights, and barriers. The TOF (Time-Off Delay) timer is one of the most prevalent automation safety devices.The doors of the machine are locked by the TOF timer, indicating that the machine has started the process, which is shown by a door locked indicator. The TOF timer then keeps the doors closed for an additional five seconds after the part is completed in order to stop the machine. As a result, the operator cannot open the door until the machine has stopped.
The TOF timer is one of the several safety devices used in manufacturing. There are other safety devices that serve a similar function to the TOF timer, such as the interlock switch, which prevents the machine from starting until the door is closed, and the safety mat, which stops the machine if someone steps on it while the machine is running.Automation is a strategy for minimizing the amount of direct human intervention required to operate and maintain machinery, equipment, and other applications. Automation in manufacturing has been employed to accomplish high-volume and high-quality production, as well as to reduce waste and labor costs. With the utilization of automation, the manufacturing process has become more efficient, cost-effective, and safe.
