Conditions Specific to Remote Teaching and Assessment 1. All students are expected to have access to a computer with following capabilities: a. reliable internet connection b. camera and microphone (your computer and/or cellphone) c. document scanning application such as Adobe Scan app (https://play.google.com/store/apps/details?id=com.adobe.scan.android&hl=en_CA) 2. All students should install VPN for remote desktop access to Concordia University computer labs https://www.concordia.ca/it/support/connect-from-home.html Once you have VPN connection to Concordia University, you can access to all available software in Gina Cody School labs by following the process described in: https://www.concordia.ca/ginacody/aits/support/faq/connect-from-home.html 3. Download Microsoft Office 365: https://www.concordia.ca/it/services/office-365education.html 4. Course specific software installation instructions: Insert instructions in here 5. All students are expected to do online, timed exams a. Both midterm and final exams will be through Moodle Quiz using live-invigilation (Alternatively) Both midterm and final exams will be through Concordia Online Exam (COLE) platform using an auto-proctoring solution. Students are encouraged to visit practice exam site to become familiar with the system. For live ZOOM based exams Please note the following with respect to online live proctored exams: • That the exams will take place during the exam period at the designated date and time set by the professor (midterm) or the Exams office (final). All exam times will be set to Eastern Standard Time. • That your image, voice and screen activity may be recorded throughout the duration of the exam. • That you must show your Concordia University Identification card to validate your identity.

COURSE OBJECTIVE Kinematic and dynamic analysis of linkages and machines is a principal step in the design process. The main objective of the course is to present fundamental principles for kinematic analysis, and synthesis of mechanisms and machines. After passing this course students should be able to find mobility of different types of mechanism, to perform position, velocity and acceleration analysis using graphical and analytical methods, to synthesize linkages, to analyze different types of gears and gear trains, to perform static and dynamic force analysis of linkages and design flywheels for different applications.

ADDENDUM ACADEMIC CONDUCT ISSUES THAT APPLY IN GENERAL The basic ten rules that make you a good engineer

The B. Eng. program is set to satisfy most of the requirements for your education and prepares you for a professional engineering career that requires dedication and knowledge. What you learn, and how you learn, will be used extensively in your engineering profession for the next 30 to 40 years. Therefore, the four years spent in the engineering program are crucial towards your professional formation. The first step is for you to learn to “think like an engineer” which means: • accept responsibility for your own learning • follow up on lecture material and homework • learn problem-solving skills, not just how to solve each specific homework problem • build a body of knowledge integrated throughout your program • behave responsibly, ethica...
