Model: Physical system CRAAP test Model description CRAAP test Model output Relate back to real system Evaluate model & argumentation References My responsibility on the team is project organizer. I am modeling the length of a high voltage cable line, when placed under specific tension. The cable can have three different possible starting length 200.2m, 200.4m and 200.6m. The cable itself is a Finch/ACSS with important characteristics including rated strength, diameter, and ampacity [1]. These characteristics were quoted from [1], which is the ALCAN cable bare overhead transmission and distribution conductor’s technical manual (2008). This is the standard manual used by engineers for specifications on all ALCAN cables, written by …show more content…
Also we must assume that no external forces are acting on the cable such as ice/snow buildup, wind, and strain over time or extra weight from animals such as birds. Under these conditions the cable can be modeled using the following equation to the right. Where LH0 is the initial length of the cable at an initial horizontal tension, H0, E is the elastic modulus of the cable, A is the cross sectional area and H is the tension in the cable. The equation to calculate LH was found in chapter 14 of the Sag and Tension Conductor Manual [2] which was written by professional consultants in 2006. The purpose of this document is to allow us to understanding the calculations necessary for multiple aspects of cable sag. The towers are 200m apart and tension is applied to the cable. If the cable acts how it is expected, it should increase in length as the tension increases. This is assuming there are no external factors affecting the wire. The figure to the right shows this
71,300 tons of structural steel, 931,000 tons of concrete 42,000 miles of cable wire weighting 11,840 tons, 4,851,700 steel rivets and 1,016,600 steel bolts were all used in the building of the Mackinac Bridge. 1,024,500 tons in total weight is what all this ends up weighting to (Mackinac Bridge 3) (Mackinac Bridge 8). The Main Mackinac Bridge towers reach 554 ft above water and 210 ft beneath the surface to bedrock (Mackinac Bridge 8). To contain temperature changes, high winds and changes of weight on the Mackinac bridge, the deck can move left or right as much as 35 ft at center span. (Mackinac Bridge 9). The total Building time of the bridge was 48 months/ 4
I have to pull two alleles (two straws) from the bag to represent one fish because fishes like humans get two alleles one from their father and one from their mother.

Cecila, all great questions! Typically advisors may desire to add more notes when initially scheduling a call back to close the business. The protocol for SOM has the advisor add those notes to their Outlook as an appointment/task. Unfortunately, if the call was redirected to another advisor, the other advisor will not have access to the appointment created in the previous advisor’s Outlook.
It is an attack by our best friends, …… and these attacks on mostly in randomly generated user name sites it was easy to short.
holds the record as the longest serving Representative in the history of the House of Representative. 84th – 115th his term from 1955 to 2015 were the dates of service.
The weakest feature of the paper is that although the formulas, presented by authors, are in general correct, but they do not support the conclusions the author extract from them, and mistake is hidden in the interpretation.

National Council Licensure Examination (NCLEX) is an examination administered by the National Council of State Boards of Nursing, Inc. to graduate nurses in the United States before they can obtain a practicing license. An NCLEX test blueprint is a document produced by NCSBN, which contains a summation of what is assessed in the NCLEX examination as well as the core values of nursing practice. The blueprint serves as a guide for aspiring nurses and nursing student who need to learn the basic requirements of nursing and nursing examination. The blueprint is valuable in exam preparation and as a study guide.
Cross elasticity = (Q2a – Q1a) ÷ (P2b – P1b) = (13,000 – 23,000) ÷ (15 – 12) =
As the conductor rotates toward 90 degrees, the component of horizontal velocity becomes. greater, thus generating a higher voltage. The voltage starts from zero, increases in a. positive direction to a maximum value at 90 degrees, decreases to zero at 180 degrees. increases in the opposite or negative direction until it attains a maximum negative value at 270 degrees, and finally decreases to zero value again at 360 degrees. It follows, then, that the induced emf can be completely described by the relation.
Therefore, the elasticities for each independent variable will need to be computed as follow because this will provide the breakdown of how each variable will represent within
Currently present are non invasive computational modelling techniques, these are very informative and display results with high levels of accuracy but they do have some drawbacks. It requires a long and dreary approach of formulating math equations which must then be followed by substantial computational efforts. Besides that, model preparations also involve time consuming efforts. In order to minimize computational run-time, certain assumptions have to be made in order to simplify the governing equations and hence expose a certain uncertainty in the results generated.
The objective of this study is to evaluate the effects of wire length and temperature of wire on electrical conductivity and resistivity.
