In this study, flat rectangular plates without cut-out which can be assumed as prefect plate sand plates with a central rectangular …show more content…
With the Kirchhoff theory, the following assumptions are also considered: The transverse shears strain is equal to zero. However ϒxy does not equal to zero. After loading right angles in the plane of the plate may not remain right angles. The plate may twist in the plane. This implies that a normal remains normal. Єx = 0 means that change in plate thickness can be neglected and normal undergoes no extension. In-plane strains Єx and Єy in the stress-strain equations is negligible and normal stress σz has no effect on in-plain strains. The calculated stress can be higher than the yield stress of the material since no yielding is taken into account in the analysis. The plate is initially flat. Therefore, the in-plane deflections in x and y directions at the mid-surface are assumed to be zero. The material of the plate is elastic, homogeneous and isotropic. These assumptions result in the reduction of a three-dimensional plate problem into a two dimensional
Stone Follari Summary In Flatland, everything is made of two dimensional shapes. Men are the polygons and women are the straight lines. Isosceles triangles make up the working class and soldiers; the sharp point made by the isosceles triangle is used as a weapon. Equilateral triangles- since they are normal- compose the merchants.
Tackling NFL Issues Mary Louise Pratt speech “ Art of the Contact zone”, discusses the depth of the contact zone and what it is. In Pratt’s understanding, a contact zone is term that refers to social spaces where cultures meet, clash, and grapple with each other, often in contexts of highly asymmetrical relations of power, such as colonialism, slavery, or their aftermaths as they are lived out in many parts of the world today.
Countless things happen every day. Some are good, some are bad. In the novel of Fallen Angles by Walter Dean Myers, the story follows young men soldiers who fight in the Vietnam War. Perry and Peewee who are from New York City and Chicago, respectively. The only reason for Perry going to Vietnam just because of paperwork mistakes.
“The Day it Rained Cats” and “The Space Rock” are great stories that will surely hook any reader the story! “The Day it Rained Cats” is about a girl named Sheera who has to overcome an obstacle, and the grandmother who must make a life-changing decision. “The Space Rock” is about a family who must make a big decision to either make millions on a meteorite, or just give it to the museum. “The Day it Rained Cats” and “The Space Rock” have very big similarities and distinct differences. One thing that is similar between “The Day it Rained Cats” and “The Space Rock”is the theme.
Zamboni! The icon of ice hokey Before going into the discussion about the thrill of being a Zamboni operator, I would like to introduce myself. I am Sam, and I love my job as a Zamboni operator. I have started this blog to introduce Zamboni, the iconic machine that has helped ice hockey become what it is today. The thrill of being a Zamboni operator can only be felt by a person that has driven a Zamboni.
Pontius especially is perplexed about if others identify him as being evil because he is cast as Pontius Pilate, the “villain” of the passion, year after year. In some of the parts he even plays the role of Satan in the Garden of Eden scene with Mary 1. Pontius’s struggle raises the question for the audience of whether or not people’s perception of us influence how we actually view ourselves. Do we need the validation from a second party to confirm our personal identity? In Part three, Pontius’s actions are especially influenced by how he feels others view him.

In 1972, the United States General Services Administration or the GSA, had established the Arts-In-Architecture program. With this program, it required all federal buildings to have 0.5 percent of their budget set aside to have a publicly sponsored art. In 1979, Richard Serra was asked by the GSA to create and install a public sculpture and he (Serra) would be paid $175,000, to aid in the creation of the structure. After a year of planning, “interviews, drafts, and reviews by both art-world appointed civilians and government officials”, the minimalist artist finally installed the sculpture Tilted Arc in the Federal Plaza in Lower Manhattan, New York City.
An example of the factor of strain theory is that it would be if an adolescent loses a part in a play because the main characters are a different race even if the teenager was the better actor. In this example, the adolescent experienced a loss of positive stimuli and the adolescent might feel a great amount of strain and believe the only way to get rid of stress is to release their stress into a delinquent act. The loss of positive stimuli can really affect juveniles especially if they do not know how to deal with the loss in a legal way. Also according to strain theorists, before losing positive stimuli the juvenile might try to find ways to prevent losing the positive stimuli. This component of strain theory could lead to revenge on the cause of the loss of stimuli or drug use to eliminate the stress.
The selection of ASTM A706 reinforcement bars were based on the recommendations of ACI 318-11 Code Section 21.1.5.2. The longitudinal mild steel reinforcement bars were extended in the entire column height (i.e., 104 in.). The longitudinal mild steel reinforcement bars
The Garcia/Godinez duo performance was just amazing and unique. The instruments they played were very different from other instruments we most of the times get to hear in our daily basis. Even though I belong to the Mexican culture, most of the instruments were new, and for some others I finally caught the names. I really appreciate the indigenous music; I feel the connection with my heritage as well as how interesting it is to see how my ancestors created such wonderful music made by such unique and creative music instruments. One of the new instruments I got to know during this music presentation was the Teponaztli, the musical bow.
Ansel Adams was an American photographer well-known for his black and white landscape photography. His work was based around the American West and national parks as he was a keen environmentalist. Some of his most famous work was that of the photographs taken at Yosemite National Park. His work is based more towards the sublime due to the nature of the landscapes he photographs such as mountains, cliffs, raging rivers etc. In the introduction to Adams’ book: The Portfolios of Ansel Adams, John Szarkowski writes, “Adams’ pictures seem as dematerialized as the reflections on still water, or the shadows cast on morning mist.”
I had first formal exposure to civil engineering in course “Architecture 1”. This course provided me the fundamental concepts of civil architectural principles such as designing procedure, architectural component’s layouts, functional spaces as well as environmental impacts. To strengthen my concepts I pursued the courses “Strength of Materials”, “Structural Mechanics” which gave me essential knowledge about the external and internal forces occuring in simple structural elements under action of various types of loading as well as fundamental concepts in structural analysis such as modellisation, classification of structures. I gained valuable exposure to the analysis of simple structures submitted to compound loadings by the application of the principle of superposition for such cases as: unsymmetric bending, combined bending and tension or compression, combined bending and torsion, general compound loading. Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures.
Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.
A parabola is a two-dimensional, symmetrical and curved line on a graph. When graphed, it forms a U-shaped line, or in other words, a mirror-symmetrical curved line that approximately makes a U-shape. All parabolas are vaguely U-shaped, and some will have a lowest point, and some will have a highest point. Those points are called the vertex (of the parabola). A parabola will always have a (single) y-intercept, and may or may not have an x- intercept.
