The History And Development Of The Football Helmet, Paul E. Quam
The History And Development Of The Football Helmet, Paul E. Quam
Theses and Dissertations
In tracing the history and development of the football helmet in its origin and evolution, the study related the changes in design of football headgear, humorous photographic plates included throughout the chronicled data depict graphically the changes which occurred. These photographs provide a proper perspective for an understanding of the present day football helmet.
An account of the explanation proffered by designers of helmets, with reference to selection of style, has been included.
Analyzing the particular details in design of football headgear, the study alludes to the different attitudes held by both coaches and players toward the game itself.
Finally, …
Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes
Liquid Particle Interaction With A Normal Shock Wave, Victor George Forsnes
Theses and Dissertations
The atomization of a liquid by an air stream has been an item of much concern in the past, and there have been numerous experimental studies of the process made in an effort to correlate liquid and air- stream physical properties into a general model which will predict the degree of and the time required for atomization for a given physical situation. The breakup of liquid drops, a major portion of the atomization process, finds application in the field of meteorology, where the formation, breakup, and shape of raindrops is an item of much concern; in the field of internal …
Residual Stresses And The Bauschinger Effect, Raymond M. Huebner
Residual Stresses And The Bauschinger Effect, Raymond M. Huebner
Theses and Dissertations
Within the last ten years there has been much interest in the field of elasto-plastic behavior of engineering materials. Hie recent popularity of the low-cost light-weight plastically designed structures has added a great deal of impetus to this interest. This thesis deals with one of the aspects of elasto-plastic behavior, namely, the distribution of the residual stresses in a simple member which has been plastically deformed in tension and/or compression,. In particular, an attempt has been made to relate these residual stresses to the well-known but little understood Bauschinger effect.
Residual Stress Distribution Changes During Dynamic Unidirectional Tensile Loading, Henry Swan Todd
Residual Stress Distribution Changes During Dynamic Unidirectional Tensile Loading, Henry Swan Todd
Theses and Dissertations
In recent years there has been much engineering effort channeled toward obtaining higher strength, lower weight and cost product designs. In pursuit of this goal some carefully designed and tested parts have catastrophically failed after a long history of repeated successful service, even though the load at the time of failure was no higher than the part had repeatedly carried previously. These mechanical failures are commonly classified as fatigue failures.

A History Of The Emery County Progress-Leader And Its Predecessors, Bruce L. Olsen
Theses and Dissertations
The purpose of this study will be to make an accurate descriptive account of past journalistic endeavors in Emery County with special emphasis placed on the characteristics of the publications. The study will attempt to illustrate the characteristics and tone of each editor's or publisher's product. Available biographical material and characteristics of publishers and editors will be listed where possible. Factors which led to launching and/or discontinuation of publication, economic factors, and special problems will be discussed where material is available to accurately do so. The study will also examine the significance of the newspapers in the change and growth …
