The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield Jan 1949

The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield

Masters Theses

"The problem to be investigated in this thesis is that of periodic heat flow in a semi-infinite solid. Periodic flow means that heat flow is a continuous function of time and repeats itself at regular intervals. A semi-infinite solid is one which is bounded by one and only one plane. This subject has received considerable attention in the field of soil temperatures, both at the surface of the earth and at various depths. The surface of the earth is subjected to temperature changes which are nearly periodic. These temperature changes take place both daily and annually. A knowledge of these …


Automatic Wheel Balancer For Automobile Wheel, Frederick Eugene Nevin Jan 1949

Automatic Wheel Balancer For Automobile Wheel, Frederick Eugene Nevin

Masters Theses

"Automobiles of today have been so constructed that greater speeds under safer conditions now exist. One of the improvements has been the low pressure tire. These tires carrying less pressure necessitates a casing of greater volume. This has created a tire of greater thickness in the axial direction but at the same time has decreased the diameter. Because of these innovations in present-day tires the author believes the wheel assembly (tire, tube, wheel, and brake drum) should be considered as a rotating cylinder not as a rotating disk. This being the case, the condition of dynamic unbalance is more critical. …


Analytical Investigation Of Thin And Moderately Thick-Walled Tubing Under Peripheral And Biaxial Loading, Frank Joseph Cizek Jan 1949

Analytical Investigation Of Thin And Moderately Thick-Walled Tubing Under Peripheral And Biaxial Loading, Frank Joseph Cizek

Masters Theses

"The problem then, resolves itself into a study of the behavior of thin-walled and moderately thick-walled cylinders under the effects of an external fluid pressure acting alone, or the effects of an external fluid pressure acting simultaneously with an axial loading. In this thesis a theoretical or analytical approach will be used. Some application and reference will be made to oil-well casings in particular, but the solutions will not be restricted to oil-well casing alone. it must be recognized that the tubing problem involves the problem of unstability before the proportional limit of the metal is exceeded and a similar …


The Application Of The Membrane Analogy To The Solution Of Heat Conduction Problems, Lloyd Hines Wilson Jan 1948

The Application Of The Membrane Analogy To The Solution Of Heat Conduction Problems, Lloyd Hines Wilson

Masters Theses

"The purpose of this investigation is to determine the feasibility of applying the membrane analogy to the solution of two-dimensional heat conduction problems. This investigation will deal only with heat conduction in the steady state through homogeneous media"--Preface, page iii.


Investigation Of The Stress-Strain Of American Standard Or National Course Bolts, Clare Jackson Thorpe Jan 1948

Investigation Of The Stress-Strain Of American Standard Or National Course Bolts, Clare Jackson Thorpe

Masters Theses

"The purpose of this investigation is to determine, if possible, a formula for the initial tensile load that will consider the Nominal Diameter of the bolt and the yield point of the material from which the bolt is manufactured; to determine, if possible, a torque stress relation, when tightening the bolt"--Preface, page iii.


Air Cooled Engine Cooling Fins Redesigned By Use Of The Membrane Analogy For Heat Conduction, Eberhard Hammel Miller Jan 1948

Air Cooled Engine Cooling Fins Redesigned By Use Of The Membrane Analogy For Heat Conduction, Eberhard Hammel Miller

Masters Theses

"The purpose of this investigation is to determine the feasibility of applying the two-dimensional heat conduction membrane analogy to the redesign of cooling fins of air-cooled engines"--Preface, page ii.
