What phenomena causes induced drag?A) The span wise flow, inward below the wing and outward above.B) Wing tanks.C) The increased pressure at the leading edge.D) Wing tip vortices.
Answers
Induced drag is caused by wing tip vortices, which are created due to the spanwise flow of air around the wing.
So, the. correct answer is D.
What's wing tip vorticesAs air flows around the wing, it creates an area of low pressure above the wing and high pressure below it.
This difference in pressure causes air to flow from the bottom of the wing towards the top, creating a vortex at the wing tip.
This vortex creates a downward force, known as induced drag, which acts against the forward motion of the aircraft.
To reduce induced drag, winglets can be added to the wing tips to disrupt the vortex and reduce the pressure differential.
Other methods include increasing the aspect ratio of the wing or using wing sweep. Efficiently managing induced drag is critical to reducing fuel consumption and increasing the range of an aircraft.

Technician A and Technician B are both correct. Leaf springs are the main suspension component on many vehicles and are composed of multiple components, including the spring eye bushings, the interleaf separators, and the spring itself.
The spring eye bushings are located between the spring and the axle, and when they wear, they can cause squeaking or rattling noises, reduced ride quality, and other handling issues. Interleaf separators, meanwhile, separate the leaves of the spring and also provide insulation from road noise and vibration. When they become worn or move, they can cause the spring to become loose and ride quality to suffer.

A straight bevel gear pair has the following data: N, = 15: No = 45: P, =6:20 pressure angle. If the gear pair is transmitting 3.0 hp, compute the forces on both the pinion and the gear. The pinion speed is 300 rpm.The face width is 1.25 in. Compute the bending stress and the contact stress for the teeth, and specify a suitable material and heat treatment. The gears are driven by a gasoline engine. and the load is a concrete mixer pro- viding moderate shock. Assume that neither gear is straddle-mounted.
Answers
The forces on the pinion and gear are 4.75 kN and 1.5 kN, respectively, and the bending stresses are 77 MPa and 9.6 MPa, respectively. A suitable material for these gears is AISI 8620 case-hardened steel.
How to compute the forces on the pinion and gear?To compute the forces on the pinion and gear, we first need to determine the torque being transmitted by the gear pair. The power being transmitted is 3.0 hp, which can be converted to 2.24 kW. The pinion speed is 300 rpm, so the torque on the pinion is:
Tp = (2.24 kW) / (2π × 300 rad/s) = 0.0119 kNm
The gear ratio is:
i = No/Np = 45/15 = 3
So the torque on the gear is:
Tg = Tp × i = 0.0356 kNm
To compute the forces on the pinion and gear, we use the formula:
Ft = (2T)/d
dp = (Np/Pd) = 15/6 = 2.5 in
Ftp = (2Tp)/dp = 4.75 kN
For the gear:
dg = (Ng/Pd) = 45/6 = 7.5 in
Ftg = (2Tg)/dg = 1.5 kN
To compute the bending stress, we use the formula:
σb = (Ks × Ft)/(J × Y)
where Ks is the stress concentration factor, Ft is the tangential force, J is the equivalent bending moment of inertia, and Y is the Lewis form factor. For straight bevel gears, the Lewis form factor is approximately 0.154.
We can assume a stress concentration factor of 1.5 and use the formula for the equivalent bending moment of inertia for a solid circular section:
J = π/32 × (d⁴ - (d - 2h)⁴)
where d is the pitch diameter and h is the height of the gear tooth. For these gears, h = 0.25P = 1.5 in.
Jp = π/32 × (2.5⁴ - (2.5 - 2 × 1.5)⁴) = 0.000250 in⁴
Jg = π/32 × (7.5⁴ - (7.5 - 2 × 1.5)⁴) = 0.0137 in⁴
For the pinion:
σbp = (1.5 × 4.75 kN)/(0.000250 in⁴ × 0.154) = 77 MPa
For the gear:
σbg = (1.5 × 1.5 kN)/(0.0137 in⁴ × 0.154) = 9.6 MPa
To compute the contact stress, we use the formula:
σc = Kc × (Ft/(bw × dp))
where Kc is the contact stress factor, Ft is the tangential force, bw is the face width, and dp is the pitch diameter.
We can assume a contact stress factor of 1.25.
For the pinion:
σcp = 1.25 × (4.75 kN/(1.25 in × 2.5 in)) = 1.52 MPa
For the gear:
σcg = 1.25 × (1.5 kN/(1.25 in × 7.5 in)) = 0.32 MPa
A suitable material for these gears would be case-hardened steel, such as AISI 8620. The heat treatment would involve carburizing the surface of the gears to a depth of approximately 0.020 in. followed by qu.

The present one is owned and operated by a local family that has lived in the area for generations, while the new one is proposed by a national restaurant chain. The airport board would like to protect the local restaurant from competition from the out-of-town chain. Can the board legally exclude a second restaurant from the airport? Explain.
There is an FBO at the airport, and another is proposed. The present one is owned and operated by a local family that has operated the FBO for generations, while the new one is proposed by an international FBO chain. The airport board would like to protect the local FBO from competition from the big chain. Can the board legally exclude a second FBO from the airport? Explain.
If either of the previous questions would violate the provisions of the town’s grant agreement with the FAA, what recourse is available to the applicant whose proposal was rejected by the board?
Answers
The airport board cannot legally exclude a second restaurant from the airport. Also, it cannot legally exclude a second FBO from the airport. The town’s grant agreement with the FAA prohibits discrimination against airport tenants.
As a requirement for accepting FAA grant funds, airports must comply with a set of terms and conditions known as "grant assurances." They assist airports in maintaining a secure, effective, and efficient airport system in accordance with federal laws and regulations. They're generally required in exchange for federal funding or for the use of federally controlled land. Grant assurances aim to assure that federal money used for airport construction is spent wisely and that airports operate in a manner that is consistent with federal objectives. They also guarantee that the airport will be open to the public and that it will operate on a non-discriminatory basis.In general, grant assurances relate to the following topics: the sale of surplus property, revenue use, fee and rental structure, operation and maintenance, airport layout plans, environmental compliance, and competition. The FAA requires airports that accept federal grants to be self-sufficient. They may do so by charging fair rents, fees, and other charges to those who use the airport's facilities and services. Additionally, FAA grant assurance prohibit airports from being biased against one tenant or industry or favoring another. Therefore, the board of the airport cannot legally exclude a second restaurant from the airport, or a second FBO from the airport.What is the recourse available to the applicant whose proposal was rejected by the board?An applicant whose proposal has been rejected by the airport board may take the following steps if they believe they have been treated unfairly:File a complaint with the FAA's Office of Civil Rights (ACR). If the complaint is accepted, ACR will investigate the matter.File a complaint with the Department of Transportation's (DOT) Office of Civil Rights. This is an option for those who don't think the FAA has handled their complaint correctly.Contact a private attorney to represent their interests in court. This is the only recourse for individuals who are dissatisfied with the results of the investigation conducted by ACR or DOT.

Block A has mass of mA = 58kg and rests on a flat surface. The coefficient of static friction between the block and the surface is 0.300. The coefficient of static friction between the rop and the fixed peg B is 0.310. The width of the block is d = 0.290m. Find the greatest mass, mC, that weight C can have such that block A does not move.
Answers
Answer:
The greatest mass, that the weight C can have such that block A does not move is approximately 23.259 kg
Explanation:
The given parameters are;
The mass of the block A= 58 kg
The coefficient of static friction between the block and the surface, \(\mu _s\) = 0.300
The coefficient of static friction between the rope and the fixed peg, B \(\mu _B\) = 0.310
Let T represent the tension in the rope
Therefore, when the rope is static, T = The normal reaction at the peg, B, \(N_B\)
The angle of inclination of the rope holding the block A = arctan(3/4) ≈ 36.87°
The length of the rope = √(0.4² + 0.3²) = 0.5
∴ sin(θ) = 3/5 = 0.6
cos(θ) = 4/5 = 0.8
The vertical component of the tension in the rope = T × sin(θ) = 0.6·T
The horizontal component of the tension in the rope = T × cos(θ) = 0.8·T
The friction force = μ×(W - 0.6·T) = 0.300×(58×9.8 - 0.6·T) = 170.52 - 0.18·T
The block will start to move when we have;
The horizontal component of the tension in the rope = The friction force
∴ 0.8·T = 170.52 - 0.18·T
0.8·T + 0.18·T = 170.52
0.98·T = 170.52
T = 170.52/0.98 = 174
Therefore, the tension in the rope = T = 174 N = The normal reaction at the peg, B \(N_B\)
The frictional force at the peg, \(F_B\) = \(\mu _B\) × \(N_B\) = 0.310 × 174 N = 53.94 N
The weight of the mass, \(m_c\), \(W_c\) = The frictional force at the peg, \(F_B\) + The tension in the rope
∴ The weight of the mass, \(m_c\), \(W_c\) = 53.94 N + 174 N = 227.94 N
Weight, W = Mass, m × The acceleration due to gravity, g, from which we have;
m = W/g
Where;
g = 9.8 m/s²
∴ \(m_c\) = \(W_c\)/g = 227.94 N/(9.8 m/s²) ≈ 23.259 kg.
The greatest mass, that the weight C can have such that block A does not move = \(m_c\) ≈ 23.259 kg.
Engineers study the properties of fluids, including viscosity and compressibility, to test the efficiency of systems under given conditions. True or False?
Answers
Answer:
True.
Explanation:
The compressibility of a fluid can be defined as a measure of the change in volume (density) with respect to the amount of pressure applied to the fluid. Thus, as the pressure of a compressible fluid increases, both its viscosity and density increases.
Some examples of compressible fluids are vapors, gases, air etc.
Additionally, the compressibility of fluids plays a significant role in the field of science such as in aerodynamics, fluid mechanics, thermodynamics etc.
Viscosity can be defined as a quantity expressing the magnitude of internal friction that restricts the ease of flow between parallel layers at some distance apart having unit speed relative to each other.
These properties of fluids, including viscosity and compressibility are usually being studied by engineers such as civil engineers, in order to test the efficiency of systems under given conditions.

all medical gas and vacuum systems shall be protected against all of the following exceptA) combustible liquids. B) corrosion. C) freezing. D) physical damage
Answers
The correct answer is A) combustible liquids. Medical gas and vacuum systems shall be protected against all of the following except A) combustible liquids. These systems need protection from B) corrosion, C) freezing, and D) physical damage to ensure proper function and safety.
Medical gas and vacuum systems are critical components in healthcare facilities, as they provide the necessary gases for medical procedures and surgeries. These systems must be reliable and safe to prevent any interruptions in patient care. To achieve this, the systems must be protected against various hazards that could cause damage or failure.
Corrosion is a common problem in medical gas and vacuum systems, which can lead to leaks and other types of failures. Corrosion can occur due to exposure to moisture, chemicals, or other factors. To protect against corrosion, medical gas and vacuum systems are typically made of materials that are resistant to corrosion, such as stainless steel, copper, or aluminum.
Freezing is another hazard that medical gas and vacuum systems must be protected against. Freezing can cause damage to the pipes and fittings, leading to leaks or other types of failures. To prevent freezing, the systems are designed to have adequate insulation and heat tracing, which maintains the temperature of the gases and prevents them from freezing.
Physical damage is another potential hazard that medical gas and vacuum systems must be protected against. Physical damage can occur due to accidental impacts or other types of external forces. To prevent physical damage, the systems are often located in areas that are not easily accessible to unauthorized personnel, and they may be protected by barriers or other types of physical protection.
On the other hand, combustible liquids are not typically a concern in relation to medical gas and vacuum systems. Therefore, the systems are not required to be protected against them. While combustible liquids can pose a fire hazard in some settings, they are not typically used or stored in areas where medical gas and vacuum systems are located.
In summary, medical gas and vacuum systems must be protected against corrosion, freezing, and physical damage, as these are common hazards that can cause damage or failure. While other hazards may be present in different settings, combustible liquids are not typically a concern in relation to medical gas and vacuum systems.

In the following load-tracing problem, construct a series of FBDs and show the propagation of loads
through the various structural elements.
Determine the column loads (A1, A3, B2, C2, D1, and D3)
Assuming:
DL (decking, flooring, etc) = 10 psf
LL (occupancy) = 40 psf
Beam B-2 spans between girder G-3 and column B-2
Beam B-3 spans between girder G-3 and column C-2
Answers
Using the equations of statics, we can solve for the reaction forces and column loads. The final results are:
RD3 = 5150 lb
R = 6950 lb
RC2 = 8400 lb
VL = 1800 lb
Define reaction force.
A reaction force is a force exerted by support on a structure or object, in response to the weight or load applied to the structure or object. In other words, it is the force that an object exerts on a support or surface that it rests upon, in order to maintain static equilibrium. Reaction forces can be either vertical or horizontal, and they are equal in magnitude but opposite in direction to the applied force. These forces are essential to keep structures stable and in balance.
Here is the solution to the load-tracing problem:
1. Free-body diagram (FBD) for column D3:
Vertical load: 40 psf
Reaction force: RD3
2. FBD for girder G3:
Vertical load: 10 psf (dead load from beam B2) + 40 psf (live load from beam B2) + 10 psf (dead load from beam B3) + 40 psf (live load from beam B3) = 1800 lb
Horizontal load: 0 lb
Reaction force: R
3. FBD for column C2:
Vertical load: 10 psf (dead load from beam B3) + 40 psf (live load from beam B3) + 10 psf (dead load from girder G3) + 40 psf (live load from girder G3) = 3150 lb
Reaction force: RC2
4. FBD for beam B3:

5. FBD for girder G2:
Vertical load: 10 psf (dead load from column B2) + 40 psf (live load from column B2) = 500 lb
Reaction force: RG2
6. FBD for column B2:
Vertical load: 10 psf (dead load from beam B2) + 40 psf (live load from beam B2) + 500 lb (vertical load from girder G2) = 2100 lb
Reaction force: RB2
7. FBD for beam B2:
Vertical load: 10 psf (dead load from beam B2) + 40 psf (live load from beam B2) = 500 lb
Horizontal load: 0 lb
Shear force: VR (vertical load from girder G3) + RB2 (vertical load from column B2)
Moment: VR * L/2 + RB2 * L/2 (where L is the span of beam B2)
8. FBD for girder G1:
Vertical load: 10 psf (dead load from column A1) + 40 psf (live load from column A1) = 500 lb
Reaction force: RG1
9. FBD for column A1:
Vertical load: 10 psf (dead load from beam A1) + 40 psf (live load from beam A1) + 500 lb (vertical load from girder G1) = 2100 lb
Reaction force: RA1
10. FBD for beam A1:
Vertical load: 10 psf (dead load from beam A1) + 40 psf (live load from beam A1) = 500 lb
Horizontal load: 0 lb
Shear force: RA1 (vertical load from column A1)

what process variable is affected when the cooling tower performance has an increase in ambient temperature that causes and increase in cooling tower demands
Answers
The process variable that is affected when the cooling tower performance has an increase in ambient temperature is lowering the efficiency of the condenser and reducing the cooling power.
The factors that is influenced performance of cooling tower are:
RangeHeat loadAmbient wet-bulb temperature or relative humidity.Approach.The temperature difference between the hot water inlet and cold water outlet at the tower is called a range. The temperature of tower's ambient is generally 4 ° C to 6 ° C (or even higher) less than the ambient temperature. Because of the temperature is cool, the cooling tower ready to cool the water at a temperature below ambient temperature. The impact of ambient temperature makes energy consumption increase.

Answers
C) Building high-morale organizations and building communication networks that include employees are both elements of employee empowerment.
Giving employees the power, responsibility, and autonomy to take charge of their own decisions and find solutions is a process known as employee empowerment. Only when an organisation has confidence in a worker's capacity for making decisions is it feasible. The organisation helps people by providing the tools they need to follow through on these choices. They don't have management or their direct supervisors controlling or interfering with their work. Employees are more likely to take ownership of their duties, become more responsible, and put forth more effort to reach their objectives when an organisation gives them greater control.
