Relation between ENTC 370 Course Objectives and MMET Program Outcomes

The Manufacturing and Mechanical ET program is designed to provide the student with several skills at the time of graduation. These skills and abilities are stated in the following MMET Program Outcomes:

A Manufacturing and Mechanical Engineering Technology graduate has the following abilities at the time of graduation:

(a) An appropriate mastery of the knowledge, techniques, skills and modern tools of manufacturing and mechanical systems and processes.

(b) An ability to apply current knowledge and adapt to emerging applications of mathematics, science, engineering and technology.

(c) An ability to conduct, analyze and interpret experiments and apply experimental results to improve processes.

(d) An ability to apply creativity in the design of systems, components or processes appropriate to program objectives.

(e) An ability to function effectively on teams.

(f) An ability to identify, analyze and solve technical problems.

(g) An ability to communicate effectively.

(h) A recognition of the need for, and an ability to engage in lifelong learning.

(i) An ability to understand professional, ethical and social responsibilities.

(j) A respect for diversity and a knowledge of contemporary professional, societal and global issues.

(k) A commitment to quality, timeliness, and continuous improvement.

(l) An ability to apply the technologies of engineering materials, manufacturing processes, automation, production operations, quality, statics, dynamics, strength of materials, fluid power or fluid mechanics, thermodynamics, and either electrical power or electronics, and statistics to the solution of manufacturing problems.

(m) An ability to apply with an added technical depth: manufacturing processes, mechanical design, electro-mechanical devices and controls (automation), and production operations.

(n) An ability to apply physics having an emphasis in applied mechanics, plus added technical topics in physics and inorganic chemistry principles related to manufacturing and mechanical systems and processes.

(o) An ability to successfully complete a comprehensive design project related to mechanical or manufacturing fields.

The following table indicates how this course contributes to the achievement of the overall programmatic educational outcomes. Entries with an “H”, “M”, and “L”, refer to high, medium, and low relevancy, respectively.

By “handouts,” I mean all materials generated for this class, which include but are not limited to syllabi, quizzes, exams, lab problems, in-class materials, review sheets, and additional problem sets.

AMERICANS WITH DISABILITIES ACT POLICY STATEMENT:

The Americans with Disabilities Act (ADA) is a Federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe that you have disability requiring accommodation, please contact the Department of Student Life, Services for Students with Disabilities, in room 126 of the Koldus Building, or call 845-1637.

ACADEMIC DISHONESTY:

For many years Aggies have followed a Code of Honor, which is stated as: “Aggies do not lie, cheat, or steal, nor do they tolerate those who do.”

The Aggie Code of Honor is an effort to unify the aims of all Texas A&M men and women toward a high code of ethics and personal dignity. For most, living under this code will be no problem, as it asks nothing of a person that is beyond reason. It only calls for honesty and integrity, characteristics that Aggies have always exemplified. The Aggie Code of Honor functions as a symbol to all Aggies, promoting understanding and loyalty to truth and confidence in each other. Effective September 1, 2004, the Office of the Aggie Honor System is operational; see http://www.tamu.edu/aggiehonor. There is a zero tolerance for academic dishonesty. Violations will be addressed by the Aggie Honor System Office and in compliance with Texas A&M Student Rules, http://student-rules.tamu.edu/rules20.htm

Disruptive behavior: If a student's behavior in class is sufficiently disruptive to warrant immediate action, the instructor is entitled to remove a student on an interim basis, pending an informal hearing with the Head of the Department offering the course. This hearing must take place within three working days of the student's removal. This rule and supporting information may be found at http://studentrules.tamu.edu/rule21.htm. Your cooperation is appreciated.

Note about isentropic compression efficiency lab: Report is now due on Wed, 11/29/06 at 5PM. I am giving more time because some of you had problems getting entropy data, etc. Feel free to contact Guillermo if you need help. Guillermo’s e-mail is: gsoriano@neo.tamu.edu

REMOTE ACCESS-HEAT TRANSFER EXPERIMENT:

Here is the experiments’ data: Heat Transfer Experiment Excel File

To be able to see data in real time, go to: http://165.91.62.107/ and download Heat_transfer_experiment2.xls. In you are downloading data from an off-campus computer, make sure to use the VPN network (otherwise, the TAMU firewall will not allow you to see the file). In that case, you will need to use a campus computer.

Notes:

Calibration equations
Make sure to use steady state values for all calculations. Steady state condition should be determined based on all temperature-time profiles only.
