Introduction to Solid Modeling using Solidworks 2012: William E Howard and Joseph C. Musto Grading Policies Your grade in BENG 499 will be a weighted average of your grades in class participation, web page updates, quizzes, homeworks, projects, and final exam as described below: Class participation, Webpage Updates, & Quizzes (15%) Quizzes will randomly be given throughout the semester. The lowest quiz grade will be dropped. Homework/Mini Projects (20%) There will be a homework assignment almost every week. Homework is due at the beginning of class, except when indicated otherwise. Late homework will not be excepted unless prior arrangements with the instructor have been made. Final Project (40%) Final Exam (25%) The final exam will be cumulative. GMU Policies and Resources for Students a. Students must adhere to the guidelines of the George Mason University Honor Code [See

http://academicintegrity.gmu.edu/honorcode/]. b. Students must follow the university policy for Responsible Use of Computing [See http://universitypolicy.gmu.edu/1301gen.html]. c. Students are responsible for the content of university communications sent to their George Mason University email account and are required to activate their account and check it regularly. All communication from the university, college, school, and program will be sent to students solely through their Mason email account. d. The George Mason University Counseling and Psychological Services (CAPS) staff consists of professional counseling and clinical psychologists, social workers, and counselors who offer a wide range of services (e.g., individual and group counseling, workshops and outreach programs) to enhance students’ personal experience and academic performance [See http://caps.gmu.edu/]. e. Students with disabilities who seek accommodations in a course must be registered with the George Mason University Office of Disability Services (ODS) and inform their instructor, in writing, at the beginning of the semester [See http://ods.gmu.edu/]. f. Students must follow the university policy stating that all sound emitting devices shall be turned off during class unless otherwise authorized by the instructor. g. The George Mason University Writing Center staff provides a variety of resources and services (e.g., tutoring, workshops, writing guides, handbooks) intended to support students as they work to construct and share knowledge through writing [See http://writingcenter.gmu.edu/]. Professional Dispositions Students are expected to exhibit professional behaviors and dispositions at all times. Core Values Commitment The College of Education & Human Development is committed to collaboration, ethical leadership, innovation, research--based practice, and social justice. Students are expected to adhere to these principles. http://cehd.gmu.edu/values/ Course Description: For the electronics portion of this course, students will design circuits containing operational amplifiers and electronic (analog or digital) components. Students will then simulate, build, and test their project. Topics include fabrication methods, the design process for engineering projects, and debugging techniques for printed circuit boards. For the mechanical design portion of this class students will use SolidWorks to create basic designs of devices. Topics include theoretical insight into the process of design and geometrical modeling and design Solidworks.

Course Objectives: 1.) Provide students with an introduction to mechanical design using SolidWork software. With this, 3D models will be designed, fabricated and analyzed. 2.) Provide students with hands-on projects and provide the tools to ensure success when

designing projects that combine electronics and mehanical parts. 3.) Students will develop an electro-mechanical prototype device based on specifications, models and other input criteria.
