Response of a nonlinear two-degree-of-freedom system subjected to an impact loadingTheisen, Jerome G. 04 August 2009 (has links)
The solution of the equations of motion of an aircraft fuselage-landing gear configuration during landings is of interest to the designer who must predict the landing loads which an airplane encounters in service. In general such solutions are difficult because of the highly nonlinear characteristics of the oleo-pneumatic shock strut which couples the lower mass of the landing gear to the fuselage.
In the past, attempts to obtain solutions by linearization of these shock strut characteristics have resulted in unrealistic predictions of landing gear motions. Therefore, it has been necessary to carry out most of the theoretical analysis associated with landing gears by means of numerical integration procedures. These numerical methods are tedious, and as a result a large portion of design work has been carried out by means of trial and error drop testing of a system of masses representative of an airplane and landing gear. This in turn has proved to be time consuming and expensive.
This paper presents a method for obtaining an analytical solution of the equations of motion for a basically nonlinear system which closely resembles an actual airplane and landing gear configuration. The nonlinear system considered has two degrees of freedom and is composed of a large mass representative of the fuselage-wing combination connected by an oleo-pneumatic shock strut to a wheel. The shock strut is assumed to have velocity-squared hydraulic damping and coulomb friction forces on the strut bearings. The nonlinear spring characteristic of the tire is represented by a sectionally linear spring.
In the first part of this paper the equations of motion for this nonlinear system are derived making use of a few simplifications which previous papers have shown to be justified. Also, the degree to which these assumptions limit the results is discussed. Next these equations of motion are solved in analytical form by a method which may be called "equivalent non linearisation." It is shown that this solution is exact only for a specific combination of impact parameters, but that for a wide range of parameters the solution describes the motion of the system adequately for design purposes. Finally, a few analytical solutions are compared with solutions obtained by numerical integration methods; and the results are compared with experimental data for a typical impact. / Master of Science

Bertolt Brecht's <i>Leben des Galilei</i>: a Mythic Dimension in Epic TheatreGhosh, Yashowanto Narayan 26 July 2018 (has links)
The history of Bertolt Brecht's play Leben des Galilei extends through the writing of its three versions during 1938 to 1955 -- a period of two decades that also encompassed the entirety of the Second World War. The period also covers the atom bomb from its development to America's use of the bomb in Hiroshima and Nagasaki, as well as the beginning of the Cold War, which included the sustained threat that nuclear weapons might be used any day. This thesis traces, and offers interpretations of, changes in Brecht's Leben des Galilei from its inception in 1938-1939 -- when the protagonist, a scientist, is portrayed in a positive light -- through the play's American version in 1947, where it bitterly accuses science and scientists of having betrayed society and humanity, and finally to its last version in 1955, where the protagonist struggles to prevent the normalization--the familiarization--of the threat of nuclear warfare.
Next to the writing of the Leben des Galilei, the thesis also focuses on the main critical readings of the play. A large fraction of the critical readings, but not all of them, interpret the play either as a judgment of science or as an invitation to pass judgment on science.
The thesis compares Leben des Galilei with three different groups of other texts.
The first comparison is with two other plays that also address the problem of science in the age of nuclear weapons, and the second comparison is with other work of Brecht himself. The first comparison leads to the observation that the muted note of optimism in the final version of Leben des Galilei is exceptional, and the second comparison to the apparently unrelated observation that it was uncharacteristic of Brecht to make explicit a certain literary allusion in Leben des Galilei. The two observations converge to a possible common explanation from a comparison with a still third group of texts, a cycle of Native American myths which appear in the oral traditions of various Native American tribes spread throughout the New World.
Finally, the thesis addresses the question of why a modern-day literary text, addressing the essentially modern problem of nuclear warfare, and addressing that problem using the essentially modern techniques of Brechtian theatre, might have structures parallel to the structures of primitive mythology.

Lecture aporétique de La décision de Bertolt BrechtBayle, Marie-Noëlle 02 1900 (has links) (PDF)
L'objectif de cette recherche est de comprendre La Décision de Bertolt Brecht par le biais de la lecture littéraire, telle que présentée dans les écrits de Bertrand Gervais. L'aporie, avec ses deux composantes que sont la contradiction et la dialectique, est identifiée comme une figure de lecture nécessaire à cette approche. La démarche aporétique d'Aristote et la dialectométhodologie de Stéphane Lupasco forment deux modalités permettant l'analyse contextuelle et l'interprétation textuelle de La Décision. Cette unique pièce de la Grande pédagogie est analysée grâce à trois couples antithétiques, soit collectif/individu, accord/désaccord et communisme/non-communisme, ce dernier couple portant aussi sur une version antérieure de la pièce. Cette recherche démontre la place ambiguë de La Décision au sein de l'œuvre brechtienne. Par ailleurs, l'étude des rapports texte/paratexte met en évidence l'influence contraire des choix éditoriaux allemands et français sur la réception du texte. Enfin, le discours esthétique et politique à la base de La Décision est déconstruit par la figure de l'aporie. En conclusion, la lecture littéraire ouvre sur une appropriation nouvelle.

Sources of cubist architecture in Bohemia : the theories of Pavel JanakŽantovská Murray, Irena, 1946- January 1990 (has links)
The sources of the theories underlying Czech Cubist architecture before World War I have been only sketchily studied to date. To analyze these theories and identify their sources, I focus on the work of architect and theorist Pavel Janak (1882-1956), an early proponent of Cubist architecture in Bohemia. The thesis incorporates my translation of Janak's unpublished journal for 1911-1914, the dominant years of Czech Cubism. Through this journal and Janak's published writings, together with an examination of his own readings, I trace the development of his theories, and situate his sources, within their historical context. Janak was no mere imitator of French Cubism but was concerned to develop innovative architecture that yet possessed both historical continuity and universal validity, thanks to its space-creating qualities. / The thesis includes a facsimile of Janak's journal with its numerous sketches, a translation en face, and a complete bibliography of his sources.

"The friendly games"?: The Melbourne Olympic Games in Australian culture 1946-1956Cahill, Shane January 1989 (has links)
Melbourne is making a concerted bid to obtain the centenary 1996 Olympic Games. While much of its bid is occupied with explanations of the city’s ability to meet the International Olympic Committee’s (IOC) requirements, it is underpinned by a common theme that the city possesses a unique quality of “Friendliness”.
