ANNOUNCEMENTS

    • MECH 206 2020.

RESEARCH PROJECT

The expected due dates regarding the project milestones are as follows (Finalized dates for 2020 semester):

Milestone Due date
CAD design March 5th
Dynamics Analysis March 20th
Manufacturing April 3rd
Experimental Validation April 24th
Scientific Reports At the end of semester
Presentations Last two weeks of classes
Demonstration Day At the end of semester

 

  •   The due dates are the same for all the project groups for now, but these dates can change for each individual group according to the discretion of the responsible TA and the instructor.

 

  • For the manufacturing portion of the project, if you want to use the machine shop and need our laboratory technician, Muzaffer Butun’s assistance, groups who contact him first will be served first. This is especially important if several groups decide to leave their manufacturing to the last minute and cannot get help in time as the machines and Muzaffer Butun might be unavailable due to crowded scheduling.

 

  • You are expected to meet with your responsible TA every week and present your progress. Please schedule a time to have your weekly meeting with your TA as soon as possible.  If a group fails to meet with their TA twice, their project grade will be zero.

 

  • If you have any complaints about your responsible TA, or a problem regarding your assigned project, please contact the instructor and voice your concerns such that immediate action can be taken from our end to help you the best way we can.

Scope and objectives of the course

MECH 206 is a fundemental course in Mechanical Engineering education and it is targeting all mechanical engineering students at Koc Univeristy. It focuses on teaching the concepts and methods on planar and three-dimensional kinematics and kinetics of particles and rigid bodies. It covers work, energy, impulse and momentum concepts

Attendance, class-works, homework, exams

Class Attendance & PS sessions
The students are highly recommended that they should not miss any lecture. Students will not be admitted into the class after the lecture is started. Other than regular class hours, there will be also problem sessions given by the teaching assistant. The students are strongly recommended not to miss any of these sessions.

Class-works
During class hours, quizzes and class assignments will be given to students, in order to make them follow the course attentively, better understand the material, and to improve their skills. All class-work will be graded, and will affect the final letter grade of each student. Class-works may or may not be given on any class day; there will be no warnings before them. They must be done during the class hours and within the classroom, unless explicitly extended as a take-home by the course instructor. Anyone who misses a class-work, even with a very legitimate reason, will not be able to submit this work later, or take a make-up for it, due to the in-class nature of this work. Instead, he/she may take a voluntary homework to compensate for this loss.
There will be many quizzes. Students will not be allowed to exchange any information during them. The course instructor may permit the students to use their notes on certain quizzes; however, sharing notes will not be allowed.
There may be occasional class assignments. As students are assumed to be in the learning phase during them, they may help each other while doing their work, and also ask for help from their instructor.

There will be no warning and/or makeup for the quizzes & assignments!!                                                    

Homeworks
Homeworks will be assigned in order to expose students to more complex problems, to give them a chance to build complete solutions to real-life cases, and to evaluate their abilities and knowledge. Students should be prepared to spend considerable time for preparing these homeworks. The students are strongly advised to work on the weekly assigned problems and ask for help from the instructor or from the TA if needed.

Research Projects
The purposes of the research projects are to expose the students in a team to the realistic and dynamic engineering systems as well as allowing them to implement their knowledge to analyze the relatively complex systems from a scientific and an engineering perspective. The dynamic engineering systems can be such as automobile suspension system, dynamics of an engine, dynamics of a robot / machine tool / automation system, dynamics of an airplane, rocket, shuttle etc., or any other engineering system that the students are interested in researching.
The students will be asked to build their own teams consists of three members. Each team will give a detailed written proposal to the instructor to inform what kind of dynamic system they wish to analyze, and what the scopes of the research will be. The proposals of the teams will be collected and considered by the instructor. The instructor will meet with each team to discuss the proposed projects. Some modifications on these proposals may be required by the instructor to set the borders of the research on a ‘reasonable’ level.
The students are expected to perform search on literature and dynamic analysis on the respective system during the semester to gain a relatively broader and deeper engineering perspective. The students may use programming languages such as Matlab, Simulink, C or LabView for the analysis if they wish.
It should be noted that one of the important objectives of performing the research projects is to give the students an opportunity to work in a team discipline. Team members are also expected to meet regularly, perhaps on weekly basis, during the semester for this research. There are requirements of a formal written report and a class presentation by each team at the end of the semester. Each member of the research project team must complete his/her part in the project to take the final exam.

Exams
Two midterms and the final for this course are similar to any other: They are entirely targeted at evaluating the performance of students. Therefore, no form of information interchange will be permitted. There will always be a reasonable time
