“Machine Design Part I” is the first course in an in-depth three course series of “Machine Design.” The “Machine Design” Coursera series covers fundamental mechanical design topics, such as static and fatigue failure theories, the analysis of shafts, fasteners, and gears, and the design of mechanical systems such as gearboxes. Throughout this series of courses we will examine a number of exciting design case studies, including the material selection of a total hip implant, the design and testing of the wing on the 777 aircraft, and the impact of dynamic loads on the design of an bolted pressure vessel.

Material Properties in Design
In this week, we will first provide an overview on the course's content, targeted audiences, the instructor's professional background, and tips to succeed in this course. Then we will cover critical material properties in design, such as strength, modulus of elasticity, and the coefficient of thermal expansion. A case study examining material selection in a Zimmer orthopedic hip implant will demonstrate the real life design applications of these material properties. At the end of the week you will have the opportunity to check your own knowledge of these fundamental material properties by taking Quiz 1 "Material Properties in Design."

Static Failure Theories - Part I
In week 2, we will review stress, strength, and the factory of safety. Specifically, we will review axial, torsional, bending, and transverse shear stresses. Please note that these modules are intended for review- students should already be familiar with these topics from their previous solid mechanics, mechanics of materials, or deformable bodies course. For each topic this week, be sure to refresh your analysis skills by working through worksheets 2, 3, 4 and 5. There is no quiz for this week.

Static Failure Theories - Part II
In this week we will first cover the ductile to brittle transition temperature and stress concentration factors. Then, we will learn two critical static failure theories; the Distortion Energy Theory and Brittle Coulomb-Mohr Theory. A case study featuring the ultimate load testing of the Boeing 777 will highlight the importance of analysis and validation. Be sure to work through worksheets 6, 7, 8 and 9 to self-check your understanding of the course materials. At the end of this week, you will take Quiz 2 “Static Failure.”

Fatigue Failure - Part I
In week 4, we will introduce critical fatigue principles, starting with fully revisable stresses and the SN Curve. Then, we discuss how to estimate a fully adjusted endurance limit. Finally, a case study covering the root cause analysis of the fatigue failure of the Aloha Airlines flight 293 will emphasize the dangers of fatigue failure. In this week, you should complete worksheets 10, 11 and 12 as well as Quiz 3 “Fully Reversed Loading in Fatigue.”

Enjoyable course, have to apply the fundamentals while solving problems and the instructor given the real world example of the failures and looking waiting for Machine Design part 2 and part 3.
от партнера PMMar 31, 2018
It was a great course. Thoroughly enjoyed it and got to learn a lot.\n\nThe case studies really helped in making life easier as it helped to understand the subject better.\n\nThank you!!
от партнера BLJun 12, 2018
Very clear in objectives and to the point when discussing problems. Lectures are not spent deriving formulas but discussing meaningful and insightful problems for the practical engineer.
от партнера VGDec 17, 2018
Very good course to refresh the fundamentals of machine design. Course content is lucid and quiz's are also very impressive. I am looking forward to enroll the next course of the series.

Excellent course, very well presented. Based on techniques used in industry. Couldn't recommend this course enough! I hope Machine Design Part II & III comes along in the near future.
от партнера JVJan 25, 2017
Excellent course. You will understand how to analyze a static load an calculate the different type of stresses (among many other things). It is not an easy course, but you will help.

Loved this course. Very informative and challenging. This course taught me concepts that are usually avoided in my collegeand the ssignments enabled me to get my fundamentals clear.
от партнера ANMar 15, 2020
This course was extremely good as my basics were weak and this course helped me to build it up from the foundation. I learned about a lot of new things and in a very calm manner.
от партнера VSMar 18, 2017
This course is both intensive and challenging. Dr. Wingate does a fantastic job with real life examples and explaining subtle points that will help get ahead in the weekly quiz.

It was wonderful course and really cleared most of the doubts which were there. The course was very much effectively presented and the assignments were of good level.

A great intro course to basic failure theories and more engineering analysis skills. There are lots of worksheets and if you do them all you'll gain from this course.
от партнера BDJul 6, 2018
Very well explained and well paced. Sometimes instructor's answers are wildly different from your own because she uses exact numbers but only writes rounded numbers.
от партнера VVAug 10, 2019
Excellent work by Dr.Kathryn Wingate. This course has been very well planned and methodically executed. Challenging Quiz's and great examples. Hoping to learn more!
от партнера XSFeb 14, 2018
Great course! I learned a lot of examples, and this course help me to make some concepts clear. It's very useful. It will help me to calculate when I am working.

Excellent course for machine design. and the students who are learning machine design in there undergraduates. Yet more topic need to be cover in machine design.
