Review

COURSE

The ability to convey technical ideas to others in the form of sketches or drawings is of utmost importance for any engineer. The course MECH 313, Machine Drawing and Design, attempts to foster this ability in Mechanical Engineering students. The course plan is structured to give the student an opportunity to immediately apply material taught during lectures in working of assignments, given during the tutorial periods. A transition from basics learned in MECH 211 towards the ability to sketch or make drawing of the students' own ideas, will be emphasized in particular. Sketches or drawings, which will give the onlooker a sense of scale (proportion), are necessary requirement for the graphic communicating skill expected out of a mechanical engineer.

TEXT BOOK

Jensen, C, Jay D. Helsel, Dennis R. Short, ’Engineering Drawing and Design’, Glencoe-McGraw-Hill, Sixth Edition, SI Metric, 1998 (Seventh Edition is Ok, if sixth is not available)

NO PHOTOCOPIES OF THE BOOK ALLOWED IN THE EXAM

SELF STUDY

The students are expected to study on the topics of weld and imperial systems. This material will be covered in the exams.

TUTORIALS

The two hours per week tutorials are conducted to give the student guidance and additional information in the preparation of assignment drawings. The tutor will be available to help getting work started and to answer questions regarding the assignments or questions arising out of material covered during the lectures.

ASSIGNMENTS Templates for the Drawing Sheet available here

There will be 8 (eight) assignments to be completed. The assignments are to be done manually or by a computer using any CAD software available to the student either at home or at the university.

The assignments will consist of small design problems based on material covered in the lectures and will be structured in such a manner that a certain proficiency in design and graphic methods will be achieved gradually.

All assignment drawings must be produced in a professional manner on good quality of paper of standard sizes not less than "A4” size (8.5”xll”) or (210x297) mm, its metric equivalent (including the computer plots). Borders and title blocks should be prepared before going to the drafting room so that valuable time is not wasted during the tutorial period. Drawings must be produced in pencil but in a printable quality such that acceptable "blue line-white prints" can be made or by use of CAD printouts. Assignments will be graded for correctness of contents, neatness of presentation and printability.

Students using edition 7, there is a problem in tables 48 and 49 in the appendix and there is no tables for bearings as well. So you can print those from here for your exams. Mech313/Table 48 & 49 and Bearings.pdf

QUIZ Solutions can be downloaded here

A number of quizzes will be given during the tutorials based on the textbook and the material covered in the previous lectures. Duration of each test would be approximately 15 minutes.

GRADING

To obtain a passing mark, students should pass all the components, namely, assignments, mid-term, quiz, project and final exam. The following grading scheme will be used for those who wrote the midterm and their grade is higher than the grade in the final:

Assignments 16% (Attending the tutorials is highly recommended)

Project 4%

Quiz 10% (best 3 of the 4 quizzes)

Midterm Exam 20%

Final Exam 50%

The following grading scheme will be used for those who do not write the midterm or their grade in the midterm is below of the one in the final test:

Assignments 16% (Attending the tutorials is highly recommended)

Project 4%

Quiz 10% (best 3 of the 4 quizzes)

Final Exam 70%

A midterm examination will be given during the Lecture week 8, in the tutorial period. Both Midterm and Final Examinations will consist of drawing and design problems similar to those solved during the tutorial sessions.

NOTE: Submitting work copied from somebody else or lending such a work to somebody (as CAD drawing files) will be penalized by assigning '0' mark to all parties involved.

In the event of extraordinary circumstances beyond the University's control, the content and/or evaluation scheme in this course is subject to change.
