Introduction
The aim of the project is to find the steady-state temperature distribution in a beam. Since it’s impossible to solve the model analytically due to the irregular geometry of the cross-section, the temperature distribution will be found using ANSYS-Mechanical to model the problem and solve using the finite element method.
The report will go through creating the beam using some pre-set values and calculating the rest using a student’s ID number and applying specific boundary conditions.
The temperature distribution will be investigated by changing the boundary conditions of the front surface and inside of the pipe to being fully insulated and later, the heat transfer coefficient will be changed from 60 to 10W/m2 with the results being recorded between changes. The differences between each changes on the model will be discussed in the results/discussion section. Model description
The beam model used to find the steady-state temperature distribution was created using the pre-set dimensions that are shown in the diagrams below: FIGURE 1: Cross section of beam FIGURE 2: Parameters of beam Source for Figure 1 & 2: Math1122 assignment 1. Images by Ding, 2015
The missing geometric values of the diagrams – l, w1, w2 – were calculated using a student ID number and the following equations: l = 14 - the last digit of the student number = 14-8 = 6m w1 = 7 + the 2nd last digit of the student number = 7+1 = 8m w2 = 1.7 + (the 2nd last
in the xy-plane is equal to the radius (R) of the beam pipe, as shown in Fig.~\ref{beampipeconversion},
I notice that angle H is in the opposite of the right angle and therefore angle H has a value of 90 degrees. This will mean that the sum of the angles that are listed as (8m - 18) and (5p + 2) will add up to 90. And since the angle (7m + 3) is opposite to the (5p + 2) angle, they're equal. Therefore (8m - 18) + (7m +3) = 90.

Thermodynamics is “the study of the effects of work, heat, and energy on a system”. In Thermodynamics to find the temperature change I will use the formula: Q=MCT. In this formula Q represents the heat added, M is the mass, C is the specific heat, and Tis the change in temperature. From using this equation I will later figure out the uncertainties I have in this experiment using the formula: Amount of DataGiven (average data/ amount of data given) then you take the given and subtract it from the answer from the formula above, lastly you add it up and square root it. Next, you put it in this form: average data ± answer using the formula above. Lastly, I will use error bars on the graphs to represent the uncertainty of the graphs. Error bars are represented by this image:
In the first chapter of the “American Indians, American Justice,” the two authors Vine Deloria, Jr. and Clifford M. Lytle, try to explain the American Indians contemporary life realities by studying the historical context of the legislations and laws concerning them, since the new Europeans settlers came and until now. The chronological examination of laws put into light the controversial relations between Americans and indigenous people and explain how the Indian dilemma was treated by Americans through time. The chapter is divided into six parts, each part runs for a defined period, and all the paragraphs rely in a way that each one is represented as a consequence of what happened in the last paragraph and a cause of what takes place
The stoic worldview that is presented in The Handbook of Epictetus can be considered a divergence from Socrates’s conception of philosophy. According to Epictetus’s Handbook, he was as a firm believer that emotions would result in errors of judgement which would essentially lead to an unhappy life. Throughout his handbook, he presents the idea of how to be a proper philosopher. He states that in order to live a happy and well life one must be emotionless and should be absent. Epictetus believed that having no emotion would lead to the ultimate Telos, being happiness. Whereas Socrates’s conception of philosophy consisted of only the truth. His ultimate Telos was eudaimonia, which is also happiness, but the way to achieve that is different. Socrates was willing to die in the name of philosophy because of how strongly he felt about it. He also believed that in order to have a good life one had to do good. Although both of their end purpose consisted of happiness, they still differed.
My hypothesis of if I measure the circumference and diameter of circular objects than the relationship of the graph should be a linear line. My hypothesis was correct because my line fit best with the linear line. The percent error of the experiment was 3.141%. A possible error could be not getting the exact number to the hundredths place. One way to change that is to get a measuring tape that has all of the numbers so that you can get an exact number to the hundredths place. From this experiment I learned that your numbers have to be exact or your percent error won’t be what you want it to be. One way to fix these error is to have the whole class measure the same objects so that you can compare your results with their results and get the exact number. To improve this
In Canada, growing industrial hemp was legalized in 1998. Eighteen years later, producers still face many challenges. Farmers first have to get a license from the government to grow hemp. Then they can only plant the seeds of specific cultivars, or types, of hemp. These specific cultivars have been approved by the Canadian government because they contain minimal amounts of THC. (THC is the psychoactive component found in marijuana.) Finally, farmers in eastern Canada face an additional challenge because very little is known about how to grow hemp in eastern Canada.
The results were taken and the specific heat capacity of the 100g brass mass were calculated. For the results to be accurate we did 5 trials and finally we had our averages which were 21, 2°C, 95, 6°C, 25, 4°C
4th grade students will be provided with shapes that they can trace on their illustrations.
Madi King & Beth Braswell December 16, 2015 ICE CREAM THERMODYNAMICS LAB Introduction- The purpose of this lab was to determine how to lower the freezing point of water in order to freeze an ice cream mixture. In ice cream making removing 1000 calories of heat from a milk/sugar mixture is removed and is then transferred to the salt/ice mixture. Energy is conserved and this meets the requirements for the first law. Heat is always moving from the hotter object to the cooler one.
Where P is the applied force, L is the length of beam, E is the modulus of elasticity of aluminum, and I is the moment of Inertia.
Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems, design of conventional space and water heating systems, cooling of electronic equipment, and many manufacturing processes (Campos 3).
