Calibration Of Weirs By Means Of Critical Flow And Specific Energy, Robert A. Rapp

Masters Theses

"For many years man has been relying more each day upon metering devices to measure the flow of fluids in industry. The orifice, orifice meter, venturi meter, pitot tube, nozzle, flume and the weir have been employed, each having its own particular advantage.

In this parade of metering progress, the contracted weir has long been the forgotten brother of the suppressed weir. In almost every textbook on hydraulics or fluid mechanics, the following words appear, "end contractions are to be avoided where the weir cannot be calibrated". This skepticism and the length or absurdity of some contracted weir formulas led …

The Effect Of Pressure Prehydration On The Strength Of Hydraulic Cement Concrete, Thomas Holmes Whitfield Jr.

Masters Theses

"It appears that the rapidity of curing and the degree or ultimate strength of concrete can be influenced by both chemical and physical factors. The main function of the physical factors involved seems to be the creating of a more intimate combination of the cement and water which are the active ingredients. For example, finer grinding of the cement would present more surface area to the water; the application of heat would decrease the amount of surface tension of the water, in addition to speeding the chemical reaction, steam under pressure would force water into the porous particles of cement; …

An Application Of Skew Frequency Curves To River Stages, Vernon A. C. Gevecker

Professional Degree Theses

"Floods have occurred in the past and will occur again in the future. References to floods are incorporated in some of the early writings of man. Unfortunately though man has recorded the event, he has seldom recorded facts whereby it is possible to determine the volume of flow or the height to which the water rose. Where man has recorded the height to which water rose, much data such as channel conditions, vegetation coverage on the flood plain, etc., remains vague or unknown.

It has been only in comparatively recent times with the advent of the steamboat that man has …

Professional Degree Theses

"The first portion of this treatise is devoted to a compilation of general knowledge concerning photographic resolution testing - an explanation of certain optical terms; the drafting of resolution targets; methods for averaging resolution values, measured at various positions on the format, to obtain one over-all value for an exposure; and a description of the factors involved in conducting the photographic operations. In the second part of the paper, analyses of the results obtained from line-target resolutions are made with the purpose of determining those combinations of aperture, filter, and shutter speed which result in high photographic resolutions. This information …

The Theory Of Limit Design As Applied To Column Analysis, John Francis Mccarthy

Masters Theses

"In any discussion of compression members of a structure, account has to be taken primarily of the relative "slenderness" or bending weakness of the member. If the member be so short that axial loading causes very slight deflection at any point throughout the member, it is usually designated a simple compression member and no account is taken of the additional stresses due to the deflection. When, however, the ratio of the length to the least radius of gyration of the member becomes so large that bending stresses cannot be ignored, the member is usually called a column and its consequent …

Flood Control With Retarding Basin Type Reservoirs In Meramec Basin, Missouri, Ilhan Kaya Ozbilen

Masters Theses

"When rainfall occurs that provides more runoff than can be carried within the normal channels of existing streams a flood results. The excess water overflows the valley lands, invades developed areas, and causes destruction of property or, in extreme cases, loss of human life...Many structures are built to control water: Waterways of proper depth and width provide arteries of transportation; water controlled and discharged through water-wheels provides power; water may be caught in storage basins and distributed for irrigation or water supply; and water that is an actual or potential source of damage or danger to property or to human …

The Development Of Plans For A National Airport For Ankara, Turkey, Mehmet Ragip Samli

Masters Theses

"'The present rapid development of general interest in aviation has brought to the front a new field of engineering. Development of the airplane has already reached a stage where the limit of its usefulness seems fixed only by the places which may be provided for taking off and landing. Due to the newness of the problem, not every one on whom responsibility rests recognizes the fact that the selection of the proper site and location for an airport is just as much an engineering problem as are its design and construction.'

The Turkish government began construction or the Ankara-Esenboga airport …

Economical Span Length Ratios For Three-Span Continuous Girder Bridges, Donald Hindrik Timmer

Masters Theses

"The three-span continuous bridge is one of the most popular bridges used by highway departments at the present time. The low first cost and overall economy combined with the pleasing appearance of this type of bridge as compared to simple span structures has led most highway departments to use continuous spans whenever conditions permit. The design of three-span continuous bridges, as well as the design of any of the other bridge types, is usually carried out as an analysis rather than a design. In the case of the three-span continuous girder, with rolled steel beams, an initial assumption as to …

The time element and weather were the essential factors in the planning. In the advanced surveying course there are eighteen …

Efficiency Of Various Types Of Reinforcement In Controlling Opening Of Cracks In Concrete Pavements, Frederick Richard Heartz

Masters Theses

"To date very little work has been done on the subject of the amount of crack opening for different loads on concrete pavement. It is a known fact that these cracks must be held together sufficiently to have aggregate interlocking action if the pavement is to transfer loads from one edge of a crack to the other. The maximum permissable [sic] opening has been set at .027 inches by the Highway Research Board. The author has attempted in this investigations (1) to determine the effect of different spacing and different sizes of longitudinal and transverse wires in controlling crack opening …

Interrelationship Of Transverse Anchorage And Adhesive Bond In Welded Wire Reinforcement, Alan Arthur Becker

Masters Theses

"...Welded Wire Reinforcement Fabric has been applied only to certain "light types" of reinforced concrete construction. It has not as yet been applied as main tension reinforcement for most concrete structures, mainly due to the fact that a thorough investigation of the potentialities and possibilities of welded wire fabric has not as yet been conducted. It is expected that the data collected in this investigation coupled with data collected in similar investigations performed at the Missouri School of Mines and Metallurgy will furnish the basis for a structural and economic comparison between welded wire fabric and ordinary reinforcing bars. The …

Design Of A Wind Tunnel For The Missouri School Of Mines And Metallurgy, William E. Speece

Masters Theses

"For some time there has been a need for a wind tunnel at the School of Mines for experimental work in the Civil and Mechanical Engineering Departments. With the expanding program and the possibility of establishing an Aeronautical Engineering School here, the need will be even more pronounced. So the problem will be of definite practical value. It was the original idea to design a small tunnel, build the tunnel, and to run a series of smoke tests on various structural models. However, after discussing the possibility of such a problem with school authorities, it was decided that if a …

The Theory Of Limit Design As Applied To The Design Of A Continuous Beam Over Three Supports, Robert F. Davidson

Masters Theses

"The theory of Limit Design is the application of the theory of Plasticity to the estimation of the actual carrying capacity of a structure. In this theory, as it is applied to statistically indeterminate structures, the areas of most unfavorable stress are allowed to be stressed beyond the yield point and into the plastic range of stress. It was formerly held that, by assuming elastic behavior, all questions of strength of materials that concern the Structural Engineer were capable of solution. However, it is now becoming recognized, from actual measurements of deformations of structures and from tests carried to near …

Recommended Procedure For The Computation Of Rights Of Way, Leon Hershkowitz

Professional Degree Theses

"This thesis sets forth a recommended procedure for the computation of areas included in "rights of way," using the principle of double meridian distances.

For a considerable number of years, it has been the opinion of the author that steps should be taken to arrive at some form of standardization in the procedures necessary in the computation of areas involving right of way and to more or less standardize legal descriptions pertaining thereto.

One need only examine the records of the various County Recorders in one particular state or in different states and he would be entirely convinced that such …

A Correlation Of Formulas For The Flow Of Fluids In Pipes, John Gorman Duba

Masters Theses

"At present there exist two quite distinct fields in fluid flow in pipes, the one in water supply and the other in the petroleum industry. It is the purpose of this paper to discuss the various pipeline flow formulas as used in both fields and to correlate the exponential type formula which is much used in practice with the Nikuradse curves obtained in the laboratory"--A Brief Historical Review, page 5.

The Establishment And Analysis Of A Triangulation System For The Teaching Of Advanced Surveying, Philip Blaine Newlin

Masters Theses

"The first thought of establishing a triangulation system for the University of Arizona student work was conceived early in the fall of 1947, when the author first learned that he would be in charge of the advanced surveying field parties during the spring semester. These men were to be instructed in the accepted manner of conducting surveys of higher order. This would include the measuring of a base line of second or first order accuracy, the turning of horizontal angles with this same degree of accuracy, the determination of the azimuth of the lines by astronomical observations, the running of …

Standardization Of No-Passing Zone Pavement Markings, Glen Nickolas Hackmann

Professional Degree Theses

"This thesis is a comprehensive treatment of present methods practiced by the various Highway Departments in the United States. It presents in particular current methods used by the State Highway Departments and the Public Roads Administration in marking no-passing zones throughout the country. For a long time it has seemed to the author that such a study was needed by both students and highway engineers. Road-design information of great value has developed over the years and often has been published but never assembled in a single orderly presentation stripped of excessive overlapping"--Preface, page ii.

Masters Theses

"Less-than-car-load (L.C.L.) freight has been and is becoming more of an acute problem with the railroads of this country. They are rapidly losing this vital and important function of their transportation service. Following, is a brief history of the railroads along with a discussion of their present day problems dealing with less-than-car-load freight service. It is believed, by the author, that a system of developing and using containers and container cars along with a pick up and delivery service will solve these problems the railroads now experience. If this method of freight transport would be adopted by the railroads, not …

The Mechanical Anchorage Value Of The Transverse Wires In Welded Wire Reinforcement Fabric, Ernst August Weinel

Masters Theses

"The tests reported in this paper were performed in an effort to secure data concerning characteristic properties of Welded Wire Reinforcement Fabric. This fabric has been used, up to the present time, primarily for temperature reinforcement. Limited attention has been focused on its potentialities for use as main tension reinforcing steel, particularly concrete highway slabs and floor slab reinforcement for buildings. The manufacturers of the Welded Wire Reinforcement Fabric believe their product can be used to better advantage as main tension reinforcement in reinforced concrete structures both from an economic and structural viewpoint, than structural steel reinforcing bars"--Object of Research, …

After drilling has proceeded to a certain depth, the sides of the bore hole apparently collapse and …

A Comparison Of The Use Of Polaroid And Colored Filters In The Multiplex Aeroprojector, Robert Greig Livingston

Masters Theses

"The purpose of this thesis is the drawing of a comparison between the use of the colored filters, which are normally employed in the multiplex aeroprojector by various mapping agencies throughout the country, and the use therein of Polaroid filters. The filters in the aeroprojector serve to break the projection of a stereoscopic pair of photographs into two impressions which are viewed separately by each eye of the observer, thus providing the main requirement for the observance of a three-dimensional effect. this stereoscopic effect is utilized in the multiplex plotting machine for the delineation of contours...In order to form a …

Floods Of May 1943 In Missouri, John August Short

Professional Degree Theses

"The year 1943 will be remembered for a long time as a year of great floods in the Middle West. Floods were occurring in some section of Missouri from April to June. The period of highest stream flow in general occurred during the month of May, and it is the May flood to which this paper pertains. It is quite possible that the importance of this flood is not generally recognized. Although everyone realizes that it was a major catastrophe, only planners for the future, particularly designing engineers, can fully appreciate the benefits which will be obtained from the information …

A Study Of The Pollution Of The Meramec River, William Quentin Kehr

Professional Degree Theses

"Early in 1940 a project was undertaken for a complete survey of the Meramec River Basin. This project, of which the pollution study was a part, was one of the most extensive surveys made of an entire river basin and included detailed studies of soil erosion, land, use, pollution, rainfall, and recreation in the Meramec Basin. The pollution study covered that portion of the Meramec River from its confluence with the Mississippi River to Steelville, a distance of about 140 river miles; the Big River from its mouth to a point west of Flat River, a distance of 107 river …

Research Investigation Of Organized Drainage Districts In Mississippi, Lee Dorsett Dumm

Professional Degree Theses

"In the early days farmers attempted to drain their land individually, but they soon found that water did not recognize property lines. One farmer would ditch his land only to find that the water from his neighbor's farm would wash over has land and fill up his ditches. Another would attempt to ditch his land, but would find that no outlet was available for his ditch unless he constructed it across the land of his neighbor. Because of such situations, groups of farmers cooperated in constructing drainage improvements. However, difficulty was encountered in reaching an agreement as to the division …
