Childhood obesity is becoming a growing problem in the United States. According to the CDC, childhood obesity has more than tripled in the past 30 years [7]. It can lead to health problems previously reserved for adults, such as diabetes, high blood pressure, and high cholesterol. For the team WiiHopp project, we plan to turn a JumpSport mini-trampoline into a controller for the Nintendo Wii console. The hope is to help turn the problem of video games and the laziness surrounding them into an active solution to combat the problem of childhood obesity.

Our goal is to produce an add-on …

Engine Simulation And Diagnostic Test Bed: Final Design Report, Jeff Lewis, Cody Scott, Todd Smith

Mechanical Engineering

The San Luis Obispo High School Automotive Technology Shop has a 1991 Buick V-6 Engine which uses the OBD-I (On-Board Diagnostics, generation one) standard for diagnostic testing and troubleshooting. In order to expand the capabilities of the Automotive Technology program and allow students to gain first-hand experience troubleshooting older OBD-I engines, the shop has a need for this engine to become part of a diagnostic and troubleshooting test bed. Some of the diagnostic tests the students will perform include checking cylinder pressure, monitoring coolant system temperatures, interpreting error codes from the OBD-I system, and conducting enhanced smog testing. All of …

Engineering On The Rose Float: Final Project Report, Stephen Boles, Garrett Dong, Peter Hoonhout

Mechanical Engineering

The purpose of this project is to design the simple mechanical movement systems of the 2012 Cal Poly Tournament of Roses Float Parade to prevent failure. Three mechanisms were designed. One of the mechanisms is a tall building that has a superhero and helicopter rotating around the top; it also has the ability to rotate the top 2/3^rds of the mechanism to a 90 degree angle to fit under a 16.5 foot bridge. Another mechanism is the cars that look like they are driving on the pod’s road surface via train tracks underneath the surface. The cars will travel …

California Polytechnic State University Wind Resource Assessment, Jason Allan Smith

Master's Theses

Wind resource assessment at California Polytechnic State University shows there is potential for wind power generation on Cal Poly land. A computational fluid dynamics model based on wind data collected from a campus maintained meteorological tower on Escuela Ranch approximately 5 miles northwest of campus suggests there are areas of Cal Poly land with an IEC Class III wind resource at a height of 80 meters above ground. In addition during the daytime when the campus uses the most energy there are large portions of land with annual average daytime wind speeds above 6.9m/s. These areas have been identified by …

Thermodynamic Based Model Eliciting Activities For Undergraduate Mechanical Engineering Education, Paul Nicholas Van Bloemen Waanders

Master's Theses

Undergraduate engineering education is designed to prepare students for their careers.  The rise of technology in modern engineering allows for a shift in the way undergraduates are prepared for the modern workplace.  Model Eliciting Activities (MEAs) allow students to think critically about their own work and allow instructors to analyze the students’ problem solving methods.  To ensure that new MEAs are as effective as possible they are subject to six basic principles: model construction, reality, generalizability, self-assessment, model documentation, and effective prototype.

This document focuses on evaluating new MEAs for their adherence to the six principles from an instructor's and …

Optimization And Modeling Tools For Telescope Hexapod Structures, Michael Edward Feeney

Master's Theses

Hexapod trusses are an important element in many mechanical design systems. The natural frequency and stiffness behavior under geometric and mass variations of such structures is largely undocumented. Furthermore, the ability to quickly model hexapod designs and explore a large design-space in finite element software packages is, in general, time consuming and inefficient. The purpose of this project was to develop software tools that made design-space exploration (modeling and simulation processes) for hexapod structures drastically more efficient. Secondly, the project included an experimental analysis portion to demonstrate the various modal study techniques and to validate finite element analysis predictions. Lastly, …

Simulation And Validation Of Two-Component Flow In A Void Recirculation System, Oscar Eduardo Daza

Master's Theses

Nuclear power plants rely on the Emergency Core Cooling System (ECCS) to cool down the reactor core in case of an accident. Occasionally, air is entrained into the suction piping of ECCS causing voids that decrease pumping efficiency, and consequently damage the pumps. In an attempt to minimize the amount of voids entering the suction side of the pump in ECCS, a Void Recirculation System (VRS) experiment was conducted for a proof of concept purpose. While many studies have been oriented in studying two-component flow behavior in ECCS, none of them propose a solution to minimize air entrainment. As a …

Mobility Aid: A Dual Purpose Walker And Scooter, Zack Blois, Robia Choi, Kristin Dills

Mechanical Engineering

The Mobility Aid project was proposed by Theresa Mortilla and Idee Shapiro. The goal of the project was to design and build a device that can quickly and easily transform between a mobility walker and an electric scooter to allow for more freedom of mobility. The inspiration for this project arose from the fact that Theresa suffers from multiple sclerosis in her legs and can only walk for about thirty minutes at a time until she gets too fatigued and must sit down and rest. This device would provide her with the ability to continue moving while giving her legs …

Implementation Of A Conrad Probe On A Boundary Layer Measurement System, Charles Rocky Ulk

Master's Theses

This thesis presents the design, calibration, and performance evaluation of a type of two-hole pressure probe anemometer known as a Conrad probe, as well as its subsequent implementation on an autonomous, compact boundary layer measurement device and its first application for subsonic in-flight measurements of a swept wing boundary layer. Calibration of the Conrad probe was accomplished using two calibration functions and a non-nulling method for resolving in-plane flow velocity direction and magnitude over a range of ±30 degrees. This approach to calibration and application offered the advantages of rapid data acquisition with lower energy consumption than alternative methods for …

Final Design Report: Vibration Table For Cvbt- Vt4 Design Team, Thomas Bevan, Matthew Laurino

Mechanical Engineering

CVBT (Center for Vocational Building Technology) teaches villagers in Northeastern Thailand how to make various concrete products. Many of these products require the use of a vibration table in order to remove air and water trapped within the concrete. Removal of these voids improves the outside surface of the molded concrete, and also allows the use of a lower water to cement ratio, allowing a much stronger finished product. The currently used vibration table (VT3) has several disadvantages associated with it, which the new table (VT4) eliminates. Compared with the VT3, the VT4 has a more rigid tabletop and improved …

Human Powered Helicopter, Brenton Haven, Daniel Hudson, Eli Knight

Mechanical Engineering

Fall of 2009, The Cal Poly Aircraft Construction club restarted Cal Poly's quest for the Sikorsky prize. The Sikorsky prize rewards the first a human powered helicopter to sustain controlled hover for one minute without stored energy. Throughout the 1980’s, Cal Poly made three attempts; the most successful being the DaVinci III. Also, the DaVinci III was the first ever publically recognized successful human powered helicopter to leave the ground. This scope of this project is to improve the DaVinci III fuselage and drivetrain for the DaVinci IV. The DaVinci IV adopts the DaVinci III system layout and improves both …
