Tile adhesive is the correct answer because it is specifically designed and used for bonding ceramic tiles on walls and floors. It is a type of glue or adhesive that provides a strong and durable bond between the tiles and the surface they are being applied to. Tile adhesive is formulated to withstand the weight and stress of the tiles, as well as the moisture and temperature changes that may occur. It is commonly used in construction and renovation projects to ensure that the tiles remain securely in place for an extended period of time.

A shear wall is a reinforced concrete wall designed to resist lateral forces along its plane. These forces can be caused by wind, earthquakes, or other external loads. The wall is constructed with additional reinforcement to provide strength and stability, allowing it to withstand these lateral forces and prevent the building from collapsing or experiencing significant damage. Shear walls are commonly used in high-rise buildings and structures where lateral loads are a concern.

The mounting height of a convenience outlet is typically 0.3m. This height is commonly used to ensure that the outlet is easily accessible and convenient for users to plug in their devices. It is a standard height that allows for easy reach without being too low or too high.

The correct answer is Excavation. When applying for a Building Permit, one of the activities that can be done and is allowed by the OBO (Office of the Building Official) is excavation. Excavation involves the process of digging and removing soil or rock from a site to create a foundation for a building or to make way for underground utilities. It is an essential step in the construction process and is typically done to prepare the site for further construction activities.

A flat slab is a type of supporting wall that does not have any supporting beams. It is a reinforced concrete slab that is supported directly on columns without the use of beams. This type of construction provides a flat ceiling and allows for flexibility in the arrangement of columns and partitions. Flat slabs are commonly used in buildings where open spaces and flexibility in layout are desired.

Zinc chromate primer is applied on steel before painting to prevent rusting. This primer acts as a barrier between the steel surface and the environment, protecting it from moisture and oxidation. Rusting occurs when iron reacts with oxygen and water, forming iron oxide. By applying zinc chromate primer, it provides a protective layer that inhibits the corrosion process, ensuring the longevity of the paint job and the steel structure.

Span length refers to the distance between two structural supports. It is the measurement of the clear space between two points of support for a bridge, beam, or any other structural element. This term is commonly used in construction and engineering to determine the appropriate size and strength of materials needed for a structure. The span length plays a crucial role in ensuring the stability and safety of the structure.

A junction box is a type of electrical box that is used to connect and protect electrical wires. It is also known as a transfer box, pull box, outlet box, or cut-out box. The purpose of a junction box is to provide a safe and secure enclosure for wire connections, preventing any exposed wires or connections that could potentially cause electrical hazards. It is typically used in residential and commercial buildings to facilitate the distribution of electrical power and ensure proper wiring connections.

The heat roofing material should be placed over the rafter. This is because the rafter is the structural element that supports the roof, and placing the heat roofing material over it ensures that it is in direct contact with the roof surface. This allows the material to effectively reflect and dissipate heat, helping to keep the interior of the building cool. Placing the material under the rafter or on the ceiling would not provide the same level of heat insulation and reflection.

To calculate the number of pieces of plyform needed, we need to consider the number of sides that need to be covered by the plyform. Each column has 4 sides, so we have a total of 6 columns x 4 sides = 24 sides. Each piece of plyform will cover 2 sides (front and back), so we divide the total number of sides by 2. 24 sides / 2 = 12 pieces of plyform needed. Therefore, the correct answer is 12 pcs.

The effective area of the wall to be plastered can be calculated by finding the total area of the walls and subtracting the area of the openings (doors and windows). The frontage and depth of the house are given as 6.5m and 11.0m respectively. The height of the walls is 2.75m. The total area of the walls is (2 * (6.5m * 2.75m)) + (2 * (11.0m * 2.75m)). The area of the main door is (0.90m * 2.10m), the area of the secondary doors is (2 * (0.80m * 2.10m)), and the area of the sliding doors is (2 * (2.50m * 2.10m)). The area of the room windows is (6 * (1.80m * 1.0m)) and the area of the toilet windows is (2 * (0.50m * 0.50m)). Subtracting the total area of the openings from the total area of the walls gives the effective area to be plastered, which is 69.20 sqm.

The term "NEMA-1" refers to a specific type of enclosure or panel board housing for circuit breakers. This type of enclosure is designed for indoor use and provides basic protection against dust and debris. It does not offer any protection against water or other liquids. Therefore, the correct answer in this case is NEMA-1, indicating that the circuit breaker is housed in a panel board with this type of enclosure.

The correct answer is "Rake." The term "rake" refers to the sloping edge of a steep roof. It is the diagonal line that runs along the edge of the roof from the eave to the ridge. The rake is typically more pronounced on gable roofs, where the roof slopes down on two sides, creating a triangular shape. The rake helps to direct water and snow off the roof, preventing damage and leaks.

Glass blocks are a type of glass that can redirect the sun's reflection. This is because glass blocks are designed with a textured or patterned surface that can scatter or diffuse the sunlight, preventing it from reflecting in a concentrated manner. The texture or pattern on the glass blocks breaks up the reflection and disperses the light in different directions, reducing the intensity of the reflection and making it less harsh. This makes glass blocks a suitable choice for applications where redirecting the sun's reflection is desired, such as in windows or walls to provide privacy or to control glare.

A circuit breaker is a device that automatically interrupts the flow of electrical current in a circuit when it detects an overload or short circuit. In elevators, circuit breakers are used to protect the equipment from overcurrents. If there is a sudden surge in electrical current, the circuit breaker will trip and cut off the power supply, preventing damage to the elevator's electrical components. This helps ensure the safety and proper functioning of the elevator system.

A steep roof is most appropriate for using shingles because shingles are designed to shed water and prevent leaks. A steep roof allows water to easily flow off the roof, reducing the risk of water pooling and causing damage to the shingles. Additionally, the angle of a steep roof helps to increase the lifespan of the shingles by reducing the amount of direct sunlight and heat exposure they receive. This helps to prevent premature deterioration and fading of the shingles.

Lightweight aggregate refers to materials used in construction that have a lower density compared to traditional aggregates. The dry, loose weight of a lightweight aggregate is an important factor to consider when determining its suitability for various applications. In this case, the correct answer is 1120 kg/m3, which indicates that the lightweight aggregate has a relatively low density. This lower density makes it useful for reducing the overall weight of structures, improving insulation properties, and enhancing the workability of concrete mixes.

The minimum water pressure required is 40 psi. This means that in order for the water to flow properly, a minimum pressure of 40 pounds per square inch is needed. Any pressure below this may result in weak or insufficient water flow.

The primary purpose of roofing is to protect a building from water and external physical elements such as rain, snow, wind, and debris. The roof acts as a barrier, preventing water from entering the building and causing damage. It also helps to shield the interior of the building from external elements that could potentially cause harm or discomfort. Additionally, a well-insulated roof can help regulate the temperature inside the building, protecting it from thermal gain. While air inflation is not directly related to roofing, it can be indirectly influenced by a well-maintained roof that prevents air leaks.

The figure below is a Globe Valve.

Tegula is the correct answer because it refers to a tapered, semicylindrical roofing tile that is laid in a position with the concave side up. This type of tile is commonly used in roofing systems, particularly in ancient Roman architecture. The term "tegula" is derived from Latin and is still used today to describe this specific type of roofing tile.

The best location for the soil stack in a building is away from the exterior wall. Placing the soil stack away from the exterior wall helps to prevent any potential leaks or blockages from affecting the structure of the building. It also allows for easier access and maintenance of the soil stack, as it is not obstructed by the exterior wall. Additionally, locating the soil stack away from the exterior wall can help to minimize any odors or noise that may be associated with its operation.

A hipped gable roof is a type of roof that combines elements of both a hipped roof and a gable roof. It has a hipped roof shape with sloping sides and a ridge at the top, but also includes a gable end on one or both sides. This design provides the benefits of both roof types, including increased stability and additional space in the attic. It is commonly used in residential and commercial buildings.

The provision states that the lateral tie spacing should not exceed 16 times the longitudinal diameter, 48 times the lateral tie diameter, or the least dimension of the column. In this case, the least dimension of the column is 500mm. Therefore, the maximum lateral tie spacing would be 16 x 500mm = 8000mm or 800cm. However, the protective covering of concrete is 40mm, so we need to subtract this from the maximum spacing. Therefore, the actual spacing distance between ties would be 800cm - 4cm (40mm) = 796cm or 79.6cm. Rounding this to the nearest whole number, the spacing distance between ties would be 80cm or 8cm. However, none of the given answer choices match this calculation, so it seems that the question is incomplete or not readable.

Inverter air conditioners are cheaper because they have a DC motor. DC motors are generally more energy-efficient and cost-effective compared to AC motors. Inverter air conditioners use the DC motor to control the compressor speed, allowing for more precise temperature control and reducing energy consumption. This makes them more affordable in the long run due to lower electricity bills. Additionally, the use of a DC motor also contributes to quieter operation and longer lifespan of the air conditioner.

R-22 is the recommended refrigerant for residential, commercial, and industrial applications using split type air-conditioning systems. R-22, also known as chlorodifluoromethane, is a hydrochlorofluorocarbon (HCFC) refrigerant that has been widely used in air conditioning systems. It has good thermodynamic properties and is compatible with the existing infrastructure. However, R-22 is being phased out due to its ozone-depleting potential, and the use of more environmentally friendly alternatives such as R-410A is encouraged.

The correct answer is Metal Cald cable. This type of cable consists of one or more conductors that are individually insulated and enclosed in a metallic sheath made of interlocking metal tape or smooth corrugated metallic tube. The metallic sheath provides protection and shielding for the conductors, making it suitable for use in industrial settings where there may be a higher risk of mechanical damage or electromagnetic interference.

The total area of the forms can be calculated by finding the area of each column and then adding them together. The area of each column can be found by multiplying the height (4.0m) by the cross-sectional dimensions (300mm x 300mm). Converting the dimensions to meters (0.3m x 0.3m), we get an area of 0.09 sqm for each column. Multiplying this by the total number of columns (6) gives us a total area of 0.54 sqm. However, since the form is made of plywood with a thickness of 2", we need to subtract the area of the plywood from the total. The area of the plywood can be found by multiplying the height (4.0m) by the perimeter of the cross-section (2 x (0.3m + 0.3m) + 2 x (0.3m + 0.3m)). This gives us an area of 1.44 sqm for each column. Multiplying this by the total number of columns (6) gives us a total area of 8.64 sqm. Subtracting this from the total area of the columns gives us 0.54 sqm - 8.64 sqm = 33.60 sqm.

The modulus of elasticity of structural steel (ASTM-A36) is 200 GPa. The modulus of elasticity is a measure of a material's stiffness and its ability to deform under stress. In the case of structural steel, a modulus of elasticity of 200 GPa indicates that it has a high stiffness and will resist deformation when subjected to external forces. This property makes structural steel an ideal material for construction and engineering applications where strength and rigidity are required.
