Simple Methods And Tables For Determining True Meridian, Howard Jones Teas

Bachelors Theses

"The ordinary methods of determining the true meridian by observation on either Polaris or the sun are so tedious to calculate that most surveyors and students dread making them. Observation on Polaris at either elongation or clumination sic require less calculation and are much simpler, but this simplicity is offset by the fact that they must be taken at an exact instant. If a cloud crosses the sky at the time, the surveyor has to wait until the next night. then again the observer must know the date, exact longitude and latitude and correct time for making the observation, and …

A Thesis Submitted To The Faculty Of Marquette University, Lester James Myers

Bachelors’ Theses

Since the commerce of a country or city determines its position in the world of finance to such a great extent, it is natural to investigate the conditions which govern the country's or city's demand for its share of this commerce, and see if the natural location, and still does not receive its share of the commerce of the country, there is a decided chance for the investigation and removal of the obstacles which are the cause of this condition.

The Design Of A Twelve Story Reinforced Concrete Warehouse, A. M. Fromherz

Bachelors’ Theses

In submitting this design I do so with the one point in view, namely, to endeavor to determine when reinforced concrete becomes impractical for design purposes.

To produce a maximum condition of loading on the lower floors I have taken up the design of a warehouse which is to carry a live and impact load of 400# per sq. ft., plus the dead load on each of the twelve floors. This condition of loading is not practical for design, but it will produce our desired conditions.

From the design it can be readily seen that the columns become excessive in …

An Investigation In Concrete, Don H. Morgan

Bachelors Theses

"It is the purpose of this investigation to determine the effect of blending a portland cement with a fine silica sand. A blended cement such as this has been used successfully and economically in several important works. The United States Reclamation Service and the Los Angeles Aqueduct commission have made use of such a blended cement in several important structures. This dilution, so to say, of the cement results is a decrease in cost without a loss of strength. In this investigation it has been assured that the cement retained on a #200 sieve is inert and may be replaced …

It was not unusual in the Spring, for the swamp to be under from two to five feet of water. …

Land Drainage In Central Iowa, Ernst Lorenze Chamberlain

Professional Degree Theses

"The problems encountered in land drainage are comparatively simple when seen from an engineering point of view. Most problems do not require a fine scientific or mathematical analysis but are rather questions to be decided by good judgment or practical common sense. The most difficult problems encountered are financial, legal and political, therefore, in this paper considerable attention is paid to the Iowa drainage law, facts learned from practical drainage men and to the organization and operation of the different financing systems for drainage"--page 1.

An Investigation Of Blended Cements, Byron Lee Ashdown

Bachelors Theses

"It is generally accepted to be a fact that the coarser particles of a cement are practically inert, and that it is only the finest particles that possess the cementing qualities. Exactly what percentage of the whole is active, or possesses the cementing properties, is not known. Since but few experiments pertaining to such have been performed there is consequently little data to be found"--Introduction, page 3.

A Study For Comparative Costs Of Flat, Short Span, Concrete Steel Highway Bridges, Thomas Purcell Mccague

Bachelors Theses

"The importance of steel in the construction of long span highway bridges is well understood, but it's cost and the constant heavy maintenance charges, or it's rapid deterioration, if not properly maintained, have caused builders of bridges to seek some other material, which is low is first cost and which will not require constant painting. Se we consider concrete and concrete steel"--page 2.

The Design Of A Reinforced Concrete Arch Highway Bridge, Clinton Dewitt Smith

Bachelors Theses

"The Subject of this theses is the Design of a Reinforced Concrete Arch Highway Bridge. In making the Design the crossing of South River Street, Austin Minn., was taken as the hypothetical location of the bridge and the design made with reference to the requirements of this location. These requirements are no more than those for an ordinary rural highway bridge. While in the city of Austin it is not in the route of travel to and from the depots and is hence not subjected to the loads due to heavy freighting. There is however a heavy rural traffic, this …

Testing Of The Racine Street Highway Bridge: City Of Milwaukee, Gardner P. Allen, Ernest Gomez Arzapalo

Bachelors’ Theses

The object of this test was to determine experimentally, the live load stresses in the main members of the Racine Street Bridge, and thus to ascertain whether or not the theoretical live and dead load stresses were greater or less than the theoretical dead load plus the actual live load stresses. If less, the bridge could not be considered safe for the traffic which it now carries. The dead load stresses in the various members were determined analytically, and to these were added the respective live load stresses obtained by this test, thus obtaining the total stress in the various …

A Study Of The Economic Design Of Short Span Girder Type Concrete-Steel Highway Bridges, Enoch Ray Needles

Bachelors Theses

"The general principles underlying the design of concrete-steel structures are quite well known. Concrete itself is a structural material which is sightly, permanent, very strong in compression, thoroughly reliable when made honestly, almost fool-proof when once allowed to "set" properly, adaptable to an almost unlimited number of uses, practically fire-proof as well as water-proof, and in addition its cost is always very reasonable. The great objection to concrete is its lack of tensile strength, and likewise its lack of elasticity and toughness. Thus it is a fortunate circumstance that which is one of the least expensive of metals, and which …

The Design Of A Dam And The Investigation Of A Water Supply For The City Of Rolla, Missouri, Frank Xavier Nachtman, Ernst Lorenze Chamberlain

Bachelors Theses

"The object of this paper is to investigate a means of supplying the City of Rolla with better water at a reasonable a price as possible. The elevation and distance of the supply from the city were very important factors,also the most economical position for the dam was to be considered. After examining several drainage basins with the above purposes in mind we selected one just west of the City on account of its convenience and high elevation. The watershed includes an area of ever eight hundred acres and is divided into two parts which come together in a narrow …

Design Of Reinforced Concrete Water Tower And Tank, Harvey Oden Garst, Pearl Frederick Michael

Bachelors Theses

"Theoretically the most economical dimension for a flat bottomed cylindrical tank would be such that the height of the tank is equal to the diameter, but such a tank does not look as well as one which has the height a little greater than the diameter and as the cost will be affected but little by making the height a few feet greater than the diameter, the most economical design will not be strictly carried out in this particular"--Data, page 1.

Graphical Representation Of Compressed Air Formulae, John Thomas Vitt, Paul Andrew Philippi

Bachelors Theses

"Air during compression and expansion obeys the same laws as do other gases and these laws have been mathematically stated by purely rational formulae. Most of these formulae are logarithmic and their use involves a considerable amount of work. The object of this thesis is to present these formulae in such form that problems involving their use may be readily and easily solved. It was decided to present them graphically and the accompanying curves are the results of our labors"--page 1.
