Hub motors are compact electric motors mounted directly on each outboard wheel hub. Utilized in Formula SAE and Formula Student vehicles, this configuration offers several advantages over traditional drivetrains, including packaging optimization within the chassis, vehicle traction, and improved efficiency. Although hub motors are not yet common in 4WD vehicles, they are being explored for use in EVs and may become more common in the future. Every year, Cal Poly Racing FSAE designs and builds a formula-style race car. To improve drivetrain performance, the team is investigating the achievability of a hub motor 4WD drivetrain, requiring extensive research, development, and …

Karst Kamp Asbestos Deposits Gallatin County, Montana
Bachelors Theses and Reports, 1928 - 1970
Karst Kamp, a southwestern Montana recreation resort, is 32 road miles south of Bozeman on the east bank of the Gallatin River in a narrow V-shaped valley flanked on the west by the rugged Madison mountain range and on the east by the equally rough Gallatin range. The asbestos deposit itself lies approximately one-half mile northwest of the ranch on a heavily timbered "Alpine-like" slope nearly 1200 feet above the floor of the valley.

The Tempering Response Of Cpm® 3v Tool Steel Investigated Through Tensile Testing And Microstructural Observations
Graduate Theses & Non-Theses
Heat treatment, tensile testing failure analysis, and microstructural evaluation of the Crucible Industries tool steel CPM® 3V was undertaken to investigate CPM® 3V’s tempering response for the following samples: As-Hardened (no tempering); tempered at 450°C, 550°C, 650°C, and 700°C; and As-Received (annealed). CPM® 3V tool steel is manufactured by Crucible Industries using their proprietary Crucible Particle Metallurgy (CPM®) technology. This material was heat-treated at four different tempering temperatures and was evaluated for tensile properties according to ASTM E8. A TMS landmark tensile fixture was used to establish the ultimate tensile strength and the yield strength of the material for the …

Wet Chemical Synthesis And Properties Of Argyrodite Sulfide Solid Electrolytes For Solid State Lithium Batteries., William Arnold
Electronic Theses and Dissertations
The commercialization of the lithium-ion battery (LIB) in 1991 was responsible for the explosion in portable electronic technologies that has been seen over the past 30 years. With the advent of electric vehicles and other high-powered technologies, there is tremendous demand for LIBs with higher energy density and high safety. To achieve this, new electrode materials must be explored. The obvious choice of anode material would be pure metal lithium, which has a theoretical specific capacity of 3860 mAh g-1 . Unfortunately, metal lithium anodes have not been widely commercialized due to their tendency to react violently with the …

Low Temperature Desiccants In Atmospheric Water Generation., Sunil Gupta
Electronic Theses and Dissertations
Surging global water demand as well as changes to weather patterns and over exploitation of natural water sources, such as ground water, has made potable water a critical resource in many parts of the World already – one rapidly heading towards a crisis situation. Desalination has been adopted as a solution – this is however energy intensive and impractical for most of the developing countries - those most in need of water. A renewable source of energy is solar thermal and solar photovoltaic. A plentiful source of water is the humidity in the atmosphere. This research is to push the …
Effects Of Chain Length, Saturation, And Bases On Saponification,
The University of Akron
Effects Of Chain Length, Saturation, And Bases On Saponification, Sarah Fenik
Williams Honors College, Honors Research Projects
This project will analyze the effects of chain length and saturation of fatty acids on saponification processes, as well as the effects of the base used in the reaction. Stearic acid, lauric acid, and oleic acid will be used for the fatty acid comparisons, and sodium hydroxide and potassium hydroxide will be used for the base comparisons. Stearic acid is considered a long chain fatty acid, while lauric acid is considered a short chain fatty acid. Oleic acid is a monounsaturated fatty acid. Five soap products are be made: sodium stearate, sodium laurate, sodium oleate, potassium stearate, and potassium oleate. …
Preparation, Cure, And Characterization Of Cyanate Ester-Epoxy Blends,

Preparation, Cure, And Characterization Of Cyanate Ester-Epoxy Blends, Donald Klosterman
Chemical and Materials Engineering Faculty Publications
Cyanate ester resins are often blended with lower cost epoxy monomers in order to modify the cost, toughness, and processing characteristics. There are also several choices of catalysts that can be used to improve processing, namely by reducing the cure temperature. This study was undertaken to illustrate how a designed experiment approach can be used to systematically investigate a wide range of material combinations and illuminate the basic cure behavior of some simple cyanate ester – epoxy blend combinations. Two commercial cyanate ester resin products were obtained. Each was blended with a bisphenol F based epoxy resin at two different …

Additive Manufacturing (AM) has, in recent years, become one of the most widespread and preferred prototyping methods. The most popular additive manufacturing method is Fused Deposition Modeling. FDM’s popularity is primarily attributed to its 3 major strengths of rapid prototyping, variability in material choice, and subject specific nature. The medical industry is one of the larger industries that has benefited from 3D printing especially in the terms of medical trainers. Unfortunately, most medical trainers that are developed (either being 3d printed or through traditional manufacturing processes) are poor substitutes for the human body. This can be attributed to either a …

The Electrical Conductivity Of The Copper-Aluminum Alloys.
Bachelors Theses and Reports, 1928 - 1970
Among the many aluminum alloys which have been studied are the binary copper-aluminum alloys. These have proven to be among the most useful of the aluminum alloys thus far worked upon.
Reinventing The Wheel,
California Polytechnic State University, San Luis Obispo
Reinventing The Wheel, Esther Unti, Ahmed Shorab, Patrick Kragen, Adam Menashe
Mechanical Engineering
Reinventing the Wheel selected tires and designed wheels for the 2018 Cal Poly, San Luis Obispo Formula SAE combustion vehicle. Available tire options were evaluated for steady-state and transient performance as well as vehicle integration. A single-piece composite wheel with hollow spokes was designed to meet stiffness, strength, and tolerance requirements. A detailed study of wheel loading and geometric structural efficiency was performed. Finite element analysis was used to iterate the geometry and laminate. A two-piece male mold was designed and machined to manufacture the wheel. Removable silicone inserts were used to create the hollow spokes.
