Evaluation Vs. Measurement Essay

ASTM STANDARDS Short introduction – ASTM standards are consensus standards for systems, services, materials and products. ‘ASTM International’ is one of the largest voluntary standard developing organization in the world. It is a non-profit organization that provides a forum for the development and publication of international voluntary standards. There are approximately 12,575 ASTM standards that operate globally. TESTING ASTM STANDARDS- Scope- There test methods help in the determining of…

Prior to field measurements (during the identification field experience), practice cover estimates were recorded randomly on the site to ensure consistency. Percentage of canopy density was measured using a convex spherical forest densiometer, instrument design to estimate…

measured with the zero on the ruler, so that students are at least introduced to the correct way of approaching measurement. However, it is important to focus more on the underlying concept, and that will require students to actually be involved in creating a conceptual framework for measurement themselves (Swan, 2001). Averill and Harvey (2010) suggest introducing students to measurement through self-made scales rather than launching into using a ruler so that they can begin to grasp an…

During the course of this practical, the different factors of a pendulum will be investigated. A pendulum is a mass held from a fixed point so it is able to swing freely, the mass swings back and forth in an arc. The formula for finding the period of a certain pendulum lies in the change of the length of string suspending the mass, and the force due to gravity where the pendulum is being used. This relationship is shown in the equationT=2π√( L/g) (Sean, 2010), as the length of the string…

Office Spaces is updating their office chairs and have decided to alter the material and cross section of the arm supports. They have requested our assistance in evaluating several materials through experiments and simulations. The purpose of this experiment is to test these various materials and to recommend a material choice and cross section geometry that will minimize deflection of the arm supports. The following sections of this memorandum will detail several facets of the experiment.…

that the findings from these surveys are based on survey estimates, because of this, the results are subject to scrutiny and uncertainty. This means rather than having the exact measurement of well-being in the United Kingdom (UK), the results should be interpreted as providing a good estimate and not as an exact measurement. The advantage of measuring well-being inequality is that you can compare the differences of well-being compared to their income between higher and lower socio-economic…

(“Wikipedia”). Typically, if one were to place a weight towards the free end of a cantilever, some bending, or flexion, would be expected. Flexion, in this case, is the action of bending or the condition of being bent (“Merriam-Webster”). Given that angle measurements are involved, a protractor is typically used to measure flexion at the bending point of the cantilever. As stated before, the fact that flexion will occur as the cantilever length changes is already known. I want to see how much…

Eljelly, (2004) explained that proficient liquidity administration includes arranging and controlling current resources and current liabilities in such a way, to the point that kills the danger of failure to meet due transient commitments and evades unnecessary interest in these benefits. The relationship in the middle of benefit and liquidity was analyzed, as measured by current proportion and money hole (money transformation cycle) on an example of business entities in Saudi Arabia utilizing…

Experiment 2: Aim: In this experiment you will determine the mass of a single drop of water by a graphical method. You will evaluate its uncertainty. Data: Table 1: Number of Drops: Mass of Beaker + drops/g (0.01g) 1 2.36 g 2 2.38 g 3 2.40 g 4 2.44 g 5 2.46 g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should…

and learning how to calculate error in an experiment when using lab equipment that involves measurement, since measurement is not always precise. A-2. Tell the reader the subject of the experiment and what the key experimental variables are. • The subject of the experiment is to practice and learn how to use some of the laboratory equipment (i.e. pipette, graduated cylinder, etc) and understand why measurement is not always precise and how to calculate errors. • The independent variables are…
