Would it be possible to build a train track that floats on water?

Sure, make the train tracks from materials that (in total) are lighter (less dense) than water. Presumably you want the train tracks to support a train as well; in that case, the weight of a certain piece of train tracks, plus the total weight of the train, should be less than the weight of the water displaced by the train tracks.

How much does asbestos super six cladding weigh?

Asbestos Super Six cladding typically weighs around 8-10 kg per square meter. However, the weight may vary depending on the specific brand and thickness of the cladding.

Is snow around foundation good?

Snow around a foundation can insulate the soil and help prevent freeze-thaw cycles, which can be beneficial in colder climates. However, excessive snow accumulation against a foundation can also put pressure on the structure and potentially cause issues such as moisture infiltration or foundation damage. It's important to monitor snow buildup and ensure proper drainage away from the foundation.

What is the value of poisson ratio for brick?

The typical Poisson's ratio for brick material is around 0.18 to 0.25, depending on the specific type of brick and its composition. This value represents the ratio of transverse strain to axial strain when a brick is subjected to a tensile or compressive load.

What is construction of spectrometer?

A spectrometer typically consists of a light source, a collimator to create a parallel beam of light, a diffraction grating or prism to disperse the light into its spectral components, and a detector to capture and measure the intensity of the different wavelengths of light. The spectrometer then produces a spectrum displaying the intensity of light at different wavelengths.

Is lacquer thinner a degreaser?

Yes, lacquer thinner can be used as a degreaser. It is a strong solvent that can effectively remove grease, oil, and other substances from surfaces. However, it is important to use it in a well-ventilated area and follow safety precautions due to its strong chemical properties.

What is porosity of brick?

Porosity of brick refers to the amount of open space or voids within the brick material. Higher porosity means more voids, which can affect properties like strength, water absorption, and thermal insulation of the brick. Brick porosity is important to consider for various applications, such as building construction, where it can impact performance and durability.

How is carbon fiber 5 times stronger than steel?

Carbon fiber is made up of carbon atoms bonded together in a specific crystal alignment, giving it its strength. The arrangement of these carbon atoms provides exceptional tensile strength, stiffness, and resistance to deformation, making it stronger than steel. Additionally, carbon fibers are much lighter than steel, providing a high strength-to-weight ratio.

What is Ballistic galvanometer Explain its construction?

A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.

What are the construction of galvanometer?

galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.

What is acoustic insulation?

Acoustic insulation is a material or barrier designed to reduce the transmission of sound between spaces or to absorb sound within a space. It is often used in construction to improve soundproofing and create quieter environments by blocking or dampening noise.

What is the purpose of prolonged application of heat on the smear?

by application of heat and a mordant, the cell can be stained. the purpose of heating is to soften the waxy material of the cell wall and allow the stain enter the cell. rock on University of Luzon!

Is justice a human construction?

Justice can be seen as a human construct because it is based on human values, beliefs, and social norms. Different cultures and societies have different understandings of justice, and it is influenced by factors like history and power dynamics. However, the concept of justice also has underlying principles of fairness, impartiality, and accountability that are considered fundamental to a just society.

What is a sentence for loose construction?

A sentence using loose construction is: Federalist believed in loose construction for the Constitution.

What is social construction?

A social construction is any institutionalized entity or cultural artifact in a social system "invented" or "constructed" by participants in a particular culture or society that exists because people agree to behave as if it exists or follow certain conventional rules. One example of a social construct is hierarchy or social status.

What does glen abbey say that visiting the glen canyon area before and after construction make him qualified to do?

Glen Abbey claims that visiting the Glen Canyon area before and after construction makes him qualified to understand the environmental impact of the construction project and the changes to the natural habitat.

What do you think was the purpose behind the construction of baolis?

Baolis, or stepwells, were built in ancient India to provide a reliable water source for drinking, irrigation, and bathing. They were also used as gathering places and served as a way to combat water scarcity in arid regions. Additionally, they often had architectural and religious significance, serving as places of worship and community gathering.

What is the system called that supports the sides of an excavation?

The system that supports the sides of an excavation is called a shoring system. It is designed to prevent the walls from collapsing and ensure the safety of workers in the excavation site. Shoring systems can be temporary or permanent, depending on the construction project.

What are the basics of theory construction?

Theory construction involves identifying a problem or question, reviewing existing literature, developing a conceptual framework, formulating hypotheses, collecting data, analyzing data, and revising the theory based on findings. The process involves building on existing knowledge, testing the theory through research, and refining it through continuous evaluation and modification. The goal is to develop a well-supported and coherent explanation for the phenomena of interest.

Why is metaparadigm necessary for theory construction?

The metaparadigm provides a foundation by defining the key concepts of a discipline, such as nursing. It helps theorists establish common language, assumptions, and values, which guide the development of theories. Without a metaparadigm, there would be confusion and inconsistency in theoretical frameworks within a discipline.

What is construction methodology?

Construction methodology is the procedure used to estimate the construction cost of a house. For instance, the construction cost of a new 4 bedroom house would be estimated by using the construction methodology.

What is construction play?

'Constructed' play is when the players build their own decks from cards they own, which can include any card from whichever sets are legal for that particular format.

This is opposed to draft or limited play, where the deck can only be built out of cards chosen from a draft pool, or from packs provided to the player.

Principle construction and working of a motor?

The Motor Principle: when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field.

The right-hand rule for force on a conductor can be used to determine the direction of the force experienced on the conductor: if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand.

The motor principle is used to form a precise definition of ampere. 1 ampere is the amount of current flowing through two straight parallel conductors 1 meter apart in a vacuum which produces a force 2 × 10-7 newtons per meter of conductor.

Analog electric meters (i.e., galvanometers, ammeters, voltmeters) operate on the motor principle. Electric motors are an important application of the motor principle. An electric motor consists of a permanent external field magnet (stator) and a coiled conducting ammeter (rotor) which is free to rotate within the field magnet. Brushes and a commutator (designed differently if A.C. or D.C. current is supplied to the armature) connect the armature to an external voltage source. The speed of rotation of a motor depends on the amount of current flowing through it, the number of coils on the armature, the strength of the field magnet, the permeability of the armature, and the mechanical load connected to the shaft.
