CALENDAR ENTRY Mechanisms and Electric Circuits is offered in two serial modules, including laboratory and workshop practice, and a team project to expose students to the concept of system integration involving electrical and mechanical systems. The electrical module provides an introduction to dc circuits, with an analysis of dc circuits used in control, measurement and instrumentation systems. The mechanism module provides an introduction to machine components such as belts, pulleys, gears, and simple linkages. The laboratory and workshop component introduces students to hands- on practice in basic laboratory instruments, tools and safety procedures. A team project involves the construction, assembly and testing of a simple mechanism. PREREQUISITES: CREDIT VALUE: Level III Physics or Physics 1051 (which may be taken concurrently) and Mathematics 1000 (which may be taken concurrently). 3 credits COURSE DESCRIPTION The broad aims of the course are to teach students 1) to learn the concepts and principles that apply to electric circuit analysis, and 2) to develop problem-solving skills by emphasizing the application of conceptual understanding to the solution of electric circuit problems.

All Electrical labs are in EN and all Mechanical labs are in EN Full participation in all labs in the course is compulsory for all students. Failure to participate in all labs may result in a mark of INCOMPLETE for the course. Students are expected to demonstrate awareness of, and personal accountability for, safe laboratory conduct. Safe work practices must be followed as indicated for individual laboratories, materials and equipment. Students must immediately report any concerns regarding safety to the teaching assistant, staff technologist, and professor. Lab manuals containing instructions for the labs are posted on the course information sites (Electric Circuits - D2L; Mechanical See course website) For the electrical labs, each experiment will be undertaken in groups of 2 students. Only one record of experimental results and one formal report per lab is expected

6 Course Outline 6 Only basic, non- programmable scientific calculators are allowed as aids during tests and exams. Other electronic aids, programmable calculators or calculators with symbolic manipulation, text storage and graphics capabilities (e.g. TI- 83 and TI- 84), as well as other aids (books, notes, formula sheets, electronic translators and devices, smart phones, etc.) are NOT allowed in term tests and final examinations. Unauthorized use of the above aids or devices during tests and examinations will be considered as an academic offence. ACADEMIC INTEGRITY AND PROFESSIONAL CONDUCT Cheating on tests and examinations, or copying laboratory reports will be dealt with in accordance with the procedures outlined under Academic Misconduct in the University Calendar. Students are expected to conduct themselves in all aspects of the course at the highest level of academic integrity. Any work for which the student is claiming credit should be original work and the source of any submitted material which is not original must be given proper credit. Any student found to commit academic misconduct will be dealt with according to the Faculty and University practices. More information is available at Students are encouraged to consult the Student Code of Conduct at and Memorial University s Code of Student Conduct at INCLUSION AND EQUITY Students who require physical or academic accommodations are encouraged to speak privately to the instructor so that appropriate arrangements can be made to ensure full participation in the course. All conversations will remain confidential. The university experience is enriched by the diversity of viewpoints, values, and backgrounds that each class participant possesses. In order for this course to encourage as much insightful and comprehensive discussion among class participants as possible, there is an expectation that dialogue will be collegial and respectful across disciplinary, cultural, and personal boundaries. STUDENT ASSISTANCE Student Affairs and Services offers help and support in a variety of areas, both academic and personal. More information can be found at
