Lavanya Menon answered |
Cant deficiency is the difference, between the equilibrium cant necessary for maximum permissible speed on a curve and actual cant provided. So if a vehicle travels at a speed higher than the equilibrium speed, cant deficiency occurs whereas if a vehicle travels at a speed lower than equilibrium speed, cant excess occurs.

Highway Expansion and Contraction Joints
Expansion and contraction joints are designed to allow for the thermal expansion and contraction of concrete pavement. These joints are important in preventing cracks and other types of damage to the pavement due to temperature changes. In the design of highway expansion and contraction joints, the spacing between joints is an important consideration.
Spacing of Joints
The spacing of expansion and contraction joints is determined by a number of factors, including the type of pavement, the expected temperature changes, and the traffic volume. In general, the spacing of joints is greater for concrete pavements than for asphalt pavements. The following are the recommended spacing of joints for highway expansion and contraction joints:
- Expansion joints should be provided every 50 meters (164 feet).
- Contraction joints should be provided every 10 meters (33 feet).
Reasons for Recommended Spacing
The recommended spacing of joints is based on a number of factors. The following are some reasons for the recommended spacing of joints:
- Expansion joints are provided at greater intervals because they are designed to accommodate greater movements due to temperature changes. This is because the concrete pavement expands more than it contracts due to temperature changes.
- Contraction joints are provided at smaller intervals because they are designed to accommodate smaller movements due to temperature changes. This is because the concrete pavement contracts more than it expands due to temperature changes.
- The spacing of joints is also affected by traffic volume. High traffic volumes can cause greater stresses on the pavement, which can lead to greater movement due to temperature changes. As a result, the spacing of joints may need to be reduced in areas with high traffic volumes.
Conclusion
In conclusion, the recommended spacing of highway expansion and contraction joints is 50 meters for expansion joints and 10 meters for contraction joints. These spacings are based on a number of factors, including the type of pavement, the expected temperature changes, and the traffic volume. The spacing of joints is important in preventing cracks and other types of damage to the pavement due to temperature changes.

Gate is the parking space for an aircraft. Number of Gate positions
For the present traffic 4 x 5 = 20 gates are needed. Therefore for future traffic (three times present traffic) 60 gates will be required. In addition some aircrafts will have higher occupancy time in future as they will be very big compared to the present traffic composition. Therefore 68 gates will be the correct choice.

The correct option for the cell address is option 'B', which is "A25".
Explanation:
A cell address in a spreadsheet refers to the location of a specific cell. In most spreadsheet software, such as Microsoft Excel, cell addresses are represented by a combination of a letter and a number. The letter represents the column of the cell, and the number represents the row of the cell.
In this case, the correct cell address is "A25". Let's break it down further:
1. Columns: The letters in the cell address represent the columns in the spreadsheet. The first column is denoted by the letter "A", the second column by "B", and so on. In this case, the letter "A" indicates that the cell is located in the first column.
2. Rows: The numbers in the cell address represent the rows in the spreadsheet. The first row is denoted by the number 1, the second row by 2, and so on. In this case, the number "25" indicates that the cell is located in the 25th row.
Therefore, the correct cell address is "A25", which represents a cell located in the first column and the 25th row.

Devanshi Iyer answered |
Wind rose diagram is used for the purpose(s) of:
1. Runway orientation:
The wind rose diagram provides valuable information about the prevailing wind patterns at a specific location. By analyzing the wind rose diagram, engineers and planners can determine the most frequent wind directions and speeds. This information is crucial for the proper orientation of runways at airports. Runways are typically designed to align with the prevailing wind direction to ensure safe takeoff and landing operations. By aligning the runways with the prevailing winds, aircraft can take off and land with minimal crosswind component, which enhances safety and efficiency.
2. Estimating the runway capacity:
The wind rose diagram also aids in estimating the runway capacity. The capacity of a runway is influenced by wind conditions as well. Strong crosswinds can reduce the effective capacity of a runway, as they may require aircraft to use a different runway or limit the maximum allowable crosswind component for takeoffs and landings. By analyzing the wind rose diagram, airport operators can assess the impact of wind conditions on the runway capacity and make necessary adjustments to ensure efficient operations.
3. Geometric design of holding apron:
The wind rose diagram is not directly used for the geometric design of holding aprons. Holding aprons are areas where aircraft wait before taking off or after landing. The design of holding aprons takes into consideration factors such as aircraft size, taxiway width, and traffic flow patterns. While wind conditions can indirectly influence the design of holding aprons (e.g., providing adequate space for aircraft to maneuver in crosswind conditions), the wind rose diagram itself is not a primary tool for this purpose.
Therefore, the correct statement is:
d) 1 alone: The wind rose diagram is primarily used for runway orientation. It provides information about prevailing wind patterns, aiding in the proper alignment of runways with the prevailing winds.

Harbour Depth and Loaded Draft
Harbour depth is the depth of water in a harbour or port, measured at a particular point below the lowest low water level. The loaded draft is the depth of a ship below the waterline when it is fully loaded with cargo. The maximum harbour depth below the lowest low water is generally equal to the loaded draft when the ship is fully loaded.
Bottom Condition
The type of bottom in the harbour also affects the maximum depth. If the bottom is soft, the maximum depth will be less than if the bottom is rock. This is because soft bottoms are less stable and can shift or settle over time.
Answer Explanation
The correct answer is option 'D' - loaded draft 1.8m when bottom is rock. This means that if the bottom of the harbour is rock, the maximum depth below the lowest low water will be equal to the loaded draft of 1.8 meters. This is because rock bottoms provide a stable foundation for the harbour and can support greater depths than soft bottoms.
Option 'A' is incorrect because a loaded draft of 1.2m would be too shallow for a harbour depth, even with a rock bottom. Option 'B' is incorrect because a loaded draft of 1.8m would be too shallow for a soft bottom. Option 'C' is also incorrect because a loaded draft of 1.5m would be too shallow for both rock and soft bottoms.
In summary, the maximum harbour depth below the lowest low water is generally equal to the loaded draft, and it is greater when the bottom of the harbour is rock than when it is soft.

The correct answer is option 'D' - loaded draft 1.8m when bottom is rock. This means that if the bottom of the harbour is rock, the maximum depth below the lowest low water will be equal to the loaded draft of 1.8 meters. This is because rock bottoms provide a stable foundation for the harbour and can support greater depths than soft bottoms.

Factors for estimating runway length for aircraft landing:
1. Normal maximum temperature:
The normal maximum temperature of the region where the airport is located is an important factor in estimating the runway length required for aircraft landing. Higher temperatures affect the air density, which in turn affects the aircraft's lift and braking performance. Higher temperatures reduce the density of air, resulting in reduced lift and longer stopping distances. Therefore, the runway length needs to be increased to compensate for the reduced performance of the aircraft in hot weather conditions.
2. Airport elevation:
The elevation of the airport is another critical factor in determining the required runway length for aircraft landing. Higher elevations result in thinner air, which reduces the aircraft's lift and performance. As the air density decreases with increasing elevation, the aircraft requires a longer runway to generate sufficient lift for takeoff and landing. Therefore, airports located at higher elevations need longer runways compared to those at lower elevations.
3. Maximum landing weight:
The maximum landing weight of the aircraft plays a significant role in estimating the runway length required for landing. The weight of the aircraft affects its landing speed, braking performance, and overall stopping distance. Heavier aircraft require longer runways to safely decelerate and come to a complete stop. The landing weight is determined by factors such as fuel load, payload, and passenger count. Therefore, the runway length needs to be sufficient to accommodate the maximum landing weight of the aircraft operating at the airport.
4. Effective runway gradient:
The effective runway gradient, or slope, is also considered when estimating the required runway length for aircraft landing. A downhill gradient can assist in reducing the required runway length by providing additional deceleration. Conversely, an uphill gradient increases the required runway length as it reduces the aircraft's braking effectiveness. The gradient of the runway, along with other factors, is taken into account to determine the overall runway length required for safe landing operations.
In conclusion, the factors that are taken into account for estimating the runway length required for aircraft landing include normal maximum temperature, airport elevation, maximum landing weight, and effective runway gradient. These factors are crucial in ensuring the safe and efficient operation of aircraft at airports.

Srestha Khanna answered |
Rotary intersections, also known as roundabouts, are circular intersections that help control traffic flow and reduce collisions. However, traffic conflicts may still occur in these areas. The traffic conflicts that may occur in a rotary intersection area are:
Merging and Diverging:
- Merging refers to the act of a vehicle entering the rotary intersection from a feeder road.
- Diverging refers to the act of a vehicle leaving the rotary intersection onto a feeder road.
- Conflicts may arise when merging or diverging vehicles do not yield to circulating vehicles or when circulating vehicles do not yield to merging or diverging vehicles.
Other possible traffic conflicts in a rotary intersection area may include:
- Crossing: When a vehicle crosses the rotary intersection to reach another road or exit.
- Merging and Crossing: When a vehicle merges onto the rotary intersection and then crosses it to reach another road or exit.
- Diverging and Crossing: When a vehicle leaves the rotary intersection and then crosses another road.
However, the correct answer to this question is option 'A', which refers to merging and diverging conflicts.

|
Milan Saha answered |
Rapid curing cutback bitumen is a type of bitumen that is blended with another substance in order to improve its curing time. In this case, the correct substance that is blended with bitumen to produce rapid curing cutback bitumen is petrol.
Petrol, also known as gasoline, is a flammable liquid mixture that is primarily used as a fuel in internal combustion engines. It is derived from crude oil through a refining process. Petrol has a low viscosity and a high volatility, making it an ideal additive for bitumen to enhance its curing properties.
Below is a detailed explanation of why petrol is used as a blending agent to produce rapid curing cutback bitumen:
1. Enhances Volatility: Petrol has a high evaporation rate due to its low boiling point. When blended with bitumen, it increases the overall volatility of the mixture. This enhanced volatility helps in the rapid evaporation of the petrol component, which accelerates the curing process of the bitumen.
2. Reduces Viscosity: Bitumen is a highly viscous material at room temperature, which makes it difficult to handle and apply. By blending it with petrol, the viscosity of the mixture is reduced, making it easier to work with. The lower viscosity also aids in the rapid penetration of the bitumen into the pavement surface, leading to faster curing.
3. Improves Adhesion: The addition of petrol improves the adhesion properties of the bitumen. It helps in better bonding between the bitumen and the aggregate particles, resulting in improved pavement performance. The enhanced adhesion also contributes to the rapid curing of the bitumen.
4. Provides Cost-effectiveness: Petrol is readily available and relatively inexpensive compared to other blending agents such as kerosene, benzene, or diesel. This makes it a cost-effective choice for producing rapid curing cutback bitumen.
In summary, petrol is used as a blending agent in the production of rapid curing cutback bitumen due to its high volatility, ability to reduce viscosity, improved adhesion properties, and cost-effectiveness. The addition of petrol enhances the curing time of bitumen, making it a suitable choice for various road construction and maintenance applications.

Flexible pavements are those, which on the whole have low or negligible flexural strength and are flexible in their structural action under the loads. The flexible pavement layers reflects the deformation of the lower layers on-to the surface of the layer. The flexible pavement layers transmit the vertical or compressive stresses to the lower layers by grain to grain transfer through the points of contact in granular structure.

Spring tides occur usually at new and full moon or rather a day or two after (or twice in each lunar month). At new moon, the sun and moon have the same celestial longitude and cross a meridian of the earth at the same instant. The sun and moon are on same side of the earth. The high water level of the resulting tide is above the average, whereas the low water level is below the average.
During neap tide, the moon falls behind the sun. High water level is below the average, whereas the low water level is above the average.
