ObjectiveThis project is an endeavor at UTSA for engineering students to be able to demonstrate costsavings analysis by using modern pump controls in a laboratory setting. This system is to beused as an instructional tool in ME 4802: Thermal Fluids Laboratory to allow students to exploreenergy savings using a VFD and give them exposure to modern pump controls used to reducepumping costs. An opportunity lies in exposing UTSA mechanical engineering students to thetheory behind a VFD. The benefits of being exposed to this type of industry equipment areinvaluable as

In this type of learning environment,there is always the risk of “missing the forest for the trees” and training students to usespecific tools in specific situations while not providing them knowledge that can appliedin other environments. Great care is taken to use tools from a variety of vendors tominimize this problem. Also the hands-on experience in the assignments and projects isbalanced with more generalized material provided in the classroom lectures. Whilestudents must learn the usage of a number of different tools, they are encouraged to domuch of this on their own. This provides an excellent opportunity to encourage

This type of device can be used in traditional classes but will be most useful for distance-learning classes because of its ability to direct the student and collect data. Introduction Before attempting any design, it is important to specify what the design will accomplish, not how it will be implemented. This is typically done with a document called a functional specification. Once it is completed (and approved by shareholders, if necessary), work can begin on the actual components that make up the design. Many

theblades are exposed to high temperatures and high rotational centrifugal forces, resultingin high stresses. As a result, the blade shrouds often crack during service and canfracture, which can lead to the failure of the turbine. The design modification of a typicalblade shroud was the subject of a major design project in the course “Finite ElementApplications in Mechanical Design,” ME 4603, at the University of Texas at SanAntonio. A study of currently used shroud configurations was conducted, and severalmodifications were investigated. Gas Turbine Materials Associates in San Antonio,Texas, provided a typical shroud, containing a partial airfoil. Careful measurements weremade, and a solid model was generated in Pro/E.

These models have only produced a modest increase inlearning or understanding. This strategy of teaching/learning suffers from designinflexibility when it becomes necessary to add or remove atoms in the crystal, or to beable to move seamlessly within a crystal in order to highlight certain areas of interest.Proposed in this study, is the construction of a virtual silicon crystal environment thatsolves all of the aforementioned problems and allows for clearer instruction and learning.This project enables students to “walk” through the crystal structure of silicon, andenables them

Achieving this goal would require an expansion of 3.5 million grosssquare feet, costing more than $1.6 billion at the current construction value.4 In terms ofenrollment, UTSA now ranks second in the University of Texas System.3 Thus, the need arises

challenge of the project was to develop a link that held thehighest load for the least weight. Students designed a link, made a rapid prototyped pattern, castthe component, prepared it for testing, and tested the link in a universal testing machine. Studentsused SolidWorks to design the link, and they were required to make a minimum of threecalculations for failure and predict the failure load and location. The cast material was Al 356.The group that developed a link with the highest load to weight ratio took advantage of the factthe Al 356 alloy may be precipitation hardened.Introduction With the impetus from ABET, the faculty, and former students to include more designwithin the curriculum, the Materials Division within Mechanical

In fact, students in somesituations are more receptive to new concepts and ideas if they are introduced by their peersinstead of their instructor.
