What is the purpose of a datum level in construction?
Everything has start from somewhere. The datum level is the best place to start
Why stress is a tensor?
Stress is a tensor because it affects the datum plane. When this is affected and it changes, it is then considered a tensor.
What does reduced level mean?
In the context of Civil Engineering, especially land surveying, Reduced Level "RL" refers to reducing (or equating) levels (elevations) to a common datum, which is either a real or imaginary location with a nominated elevation of zero. The most common convenient datum was mean sea level. On small surveys that require the collection of elevation data the datum can be assumed and for practical purposes it simply needs to be far enough below the survey area to avoid negative numbers, thus the starting point of a survey might be nominated to be RL 100.00
What is the work done in raising from the ground a brick wall of uniform thickness of height 2meter and 1000kg?
The work done in raising any object from the ground is independent of the nature of the object (its composition and girth). Hence the data provided ("brick wall of uniform thickness of height 2meter [sic]") is irrelevant. The work that is done in "raising from the ground" any object massing 1000kg is the same as the work done raising any other object massing 1000kg the same distance, for example, five pecks of osmium fashioned into the death mask of Albert Einstein.It should be noted that the expression "to raise a wall" is sometimes used to mean the same thing as "to erect a wall", which clearly not at all the same thing as "to lift a wall". The point of idiotic exercises such as this is the entertainment of idiots and so the fact that terms are employed which are vague and consequently readily misinterpreted is to be expected. When human lives are at stake, for example in the design of bridges, such vagueness can have consequences which most people do not find amusing, for example, the death of the man and woman who conceived one.The answer is 9806.65 Newton-meters per meter raised (a datum not provided). This neglects the lift, which cannot be calculated without knowing the thickness and length of the wall. likewise data not provided. The wall displaces a volume of air (which weighs about one gram per liter), and the work done is less as a result. The effective mass is the mass of the wall, less the mass of the air it displaces. Since the air mass displaced is a function of altitude the solution to the problem requires calculus. Similarly, the gravitational force exerted per kilogram of mass declines as the wall is lifted and a careful calculation of the work performed must take that into account as well. Since both of these quantities vary *within the range specified as 2meters from top to bottom* the problem is quite intricate when fully fleshed unless one makes simplifying assumptions (the force of gravity is the same throughout the wall, etc.) to obtain an approximation rather than the most precise answer possible.
A primary datum requires how many points of contact?
According to ASME Y14.5, a primary dimensioning datum requires at least 3 points of contact to establish the datum plane. Two points of contact are required for the secondary datum and 1 point of contact is required for the tertiary datum.

What is the definition of 'datum' surfaces?
Datum surfaces are reference surfaces used in engineering and manufacturing to establish a common point for measurements and alignments. They provide a consistent and uniform starting point for design and quality control processes. Examples include planes, lines, and points from which other measurements are made.
In a building plan what does 1.27 meters AOD mean?
above ordnance datum!
What is datum shift?
Datum shift refers to the adjustment of coordinates from one geographic datum to another. This is necessary when working with maps or geographic data collected using different reference points, such as changing from NAD27 to WGS84. Datum shifts ensure that spatial information is accurately aligned across different datasets.
How do you select and establish a suitable datum?
Selecting and establishing a suitable Datum is critical, ensure your datum is at a fixed point. Normally a hole/slot. Holes and slots a normally lasor cut, ensuring they are at an extremely high tolorance already. Then reference the slot or hole to another near by slot or hole. Using these selected points will give you accruate points of measurement/datum.
Explain how to select and establish a suitable datum the importance of ensuring that marking out is undertaken from the selected datum and the possible effects of working from a different?
To select a suitable datum, consider a stable reference point on the workpiece or surface. Mark the datum clearly and securely. When marking out, ensure all measurements and reference points are taken from this datum to maintain accuracy and consistency. Working from a different datum can lead to incorrect measurements, misalignments, and errors in the final product. It is crucial to avoid this by consistently using the established datum.
What is the basis for all horizontal control stations?
horizontal datum note. good luck on NovaNet!
Is datum the plural of data?
Datum is not the plural of data. Datum is singular, and its plural form is data.
What is hydrography datum?
Correction: What is hydrographic datum? not "hydrography"
How is the reference datum point on aircraft determined?
It is entirely up to the manufacturer of the aircraft. Usually it is an imaginary point forward of the nose of the aircraft and all points aft of that datum have a positive value. This makes weight and balance calculations easier as there are no negative numbers.
How much does map datum influence coordinates?
Map datum plays a crucial role in determining the accuracy and consistency of geographic coordinates. Different map datums have varying ellipsoid models and reference points, which can result in significant discrepancies in coordinates if not properly accounted for. It is essential to use the correct map datum for a specific region to ensure precise positioning data.
