Structural and modal analysis of FSAE space frame chassis Aakash.V1 & Gokul Krishnakumar2 1&2School of mechanical and building sciences, VIT University, Vellore, India aakashv2014mcd0018@vit.ac.in Abstract : This paper aims to improve the stability of the race car design under various load conditions. Two basic analyses were done using Finite Element Model (FEM) techniques such as static structural and modal analysis to optimize the design of the frame especially used for Formula SAE/ Formula Student chassis. Analysis is done for improving the torsional stiffness of the frame which results in quick response during manoeuvring and the front impact, side impact and rear impact of the space frame to improve the safety features. The analysis is done on dynamic load factor which varies time to time. The worst case scenario is considered for all the above case. The dynamic load transfer and lateral load transfer are calculated to apply loads for analysis. Modal analysis is done with three types of assumption. Initially the analysis are done by applying loads to the suspension mounting points(translational) , later the whole space frame is considered as the torsional bar and finally both translational and torsional are combined together for the analysis. Keywords — Finite element model, chassis, …show more content…
Applying boundary conditions plays a vital importance in producing FEA result. The boundary conditions and loads applied will decide the torsional stiffness value calculated using the FE method. The boundary conditions in this analysis have been kept the same so as to compare the successive design iterations. Without common boundary conditions and load cases torsional stiffness values would vary and a comparison would be absurd and meaningless. Various load factors is applied to the chassis to arrive the stress and deformation of the chassis. In the following section it is
Rhetorical Analysis An ad that takes up less than half of a page, boxed off by a white boarder, letting the viewer almost see the other side of the page.

A Rhetorical Analysis “America’s Most Overrated Product: The Bachelor’s Degree” A bachelor’s degree just to drive a taxi cab? It might be the future of many college graduates according to Marty Nemko. In a June, 2008 edition of the Chronical of Higher Education in an article titled “America’s Most Overrated Product: The Bachelor’s Degree” Nemko argues that a four year college degree may not be worth the cost, and not the right choice for most high school graduates. For past generations, it has been expected that to be successful one must attend a four year university.
Corresponding ideas and uses of rhetorical devices can bridge together multiple stories. The themes of interdependence on other human beings and essentials of life are shown throughout the novels “102 Minutes” by Jim Dwyer and Kevin Flynn, and “Into the Wild” by Jon Krakauer. One may think that these pieces have nothing in common, but in order to interpret the overlying ideas, readers must look deeper than the main ideas of each book to figure out how they develop upon one another. The stories “Into the Wild,” and “102 Minutes” both use a plentiful amount of overarching viewpoints and many of the same tools of rhetoric, such as word choice, delivery and style to help expand and make connections between novels. Jon Krakauer’s purpose for “Into
Kathryn Stockett successfully uses rhetorical devices to get the reader to feel and understand the perspectives of the protagonists. Stockett uses pathos, ethos, and logos in her book, since the book about social injustice. The topics in the book range from inequality of the sexes to social classes and racism, Stockett is successful in getting the reader to reflect while reading the book and the themes of the book have a clear presence. We see Stockett use ethos and pathos in the very first chapters when we learn that Hilly doesn't like Minny and Minny doesn't want to say why at first, but the incident with Ms. Holbrook was affecting her chances of getting a job because of the influence Hilly has over this suburban society. In some instances where Stockett uses ethos, pathos is also included in her writing.
Rhetorical Analysis of A Modest Proposal In one of the most famous and most skilled pieces of satirical writing, "A Modest Proposal," Jonathon Swift aims to reveal a number of social problems that were going on in Ireland during the eighteenth century. These problems included overpopulation, starvation, and poverty. In order to accomplish his goal of bringing attention to these problems, Swift assumes the role of an economic planner who is very impersonal, objective, and insensitive. Three elements that convey the difference between the narrator 's proposal and Swift 's actual purpose include the satirical character of his tone, the ironical humor in his outrageous solutions to expose the prejudice against the poor Irish people by taking extreme measures, and the use of diction to dehumanize the
In Project #1, I chose to make a rhetorical analysis of a chapter from Jason Fagone 's book Ingenious: A True Story Of Invention, Automotive Daring, And The Race To Revive America, "How to spend your entire income building a car to travel 100 miles on a gallon of gas. " The first chapter mainly focuses on two main characters: Kevin and Jen. Mr. Fagone introduces us to them by telling us how they both met, grew up, where they went to school and what for, where they worked, and how they started working together on building the car for X Prize. Now, since my goal for this blog is to see my progress and journey to becoming a better science writer, I started reading the chapter over and over. In the beginning, I thought that "Writing for Science"

The Irony of Modesty: An Analysis of a Satirical Speech “A Modest Proposal” written by Jonathan Swift in 1729 begins by deploring indigent Irish families who struggle tirelessly to make an honest living for their large families. This speech pivots on an satirical structure with its use of rhetoric that utilizes the form of ethos, an appeal to the reader's sense of ethics and moral values held throughout Irish society. Pathos, an appeal to invoke countless emotional responses from the readers, and logos, the appeal of logic-statistics that the above subject carries to persuade an audience by reason. By using doublespeak, Swift alludes to different types of rhetoric used throughout this speech such as ironic positive slanting, charged language and even satire to exaggerate and expose the stupidity people exemplify when offering solutions regarding the political issues Ireland was dealing
Through the unequivocal lyrics of her song, “Scars to Your Beautiful,” Alessia Cara uses the rhetorical appeal of pathos to condemn society’s views of beauty in the form of body image as portrayed by the media. In this song, Cara addresses the ridiculous standards to which young people, especially women, are held. The lyrics of this song speak blatantly to the listener, as Cara criticizes the way that the media glorifies outward beauty as a god in the line, “She craves attention, she praises an image.” She then reinforces the idea that society believes that beauty is worthy of worship by asserting “She prays to be sculpted by the sculptor.” In this line, she is comparing a girl to a sculpture.
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.
