Mechanical design principles. Design, manufacture and assembly of basic machine elements. Machine frames, welded, adhesive and bolted joints, fasteners. Stepped shafts and features, rolling element bearings; gear mechanics and manufacture. Design for strength, design for other mechanical failure modes including fatigue, stress concentration. Safety, ergonomics and standards.
This course introduces students to basic principles of mechanical design relevant to industrial practice. The contents include the design of specific machine components such as power transmission gearboxes containing gears, belts, chains and pulleys, rotating shafts, keys and splines, bearings, clutches and seals,ﾠand gearboxes. Also included are: design of machine frames and assemblies including steel structures, fasteners and welded joints; considerations of safety and compliance with standards; assessment of mechanical failure (especially yielding, buckling, fracture and metal fatigue) in the context of machine design; fracture mechanics; and material properties most relevant to mechanical design; principles of sustainable design and social and environmental responsibilities of mechanical designers.
Course requirements
Assumed background
This course will be building on what you have learned in the previous courses on engineering mechanics.ﾠ Theﾠ analysis skills in engineering mechanicsﾠ will ﾠbe indispensable in analysing the loads on the machine elements you will learn to design in this course. ﾠIt is assumed that youﾠare familiar with two and three-dimensional states of stress, and with stress, deflection, and buckling analysis of beams. It is also assumed you have acquired a basic understanding ofﾠ manufacturing processes and knowledge of engineering materials and material properties. Finally, ﾠthis is an integrativeﾠ course that can potentially draw on any other material that youﾠhave learned in your first two years of study.
Prerequisites
You'll need to complete the following courses before enrolling in this one:

Aims and outcomes
This course is an important milestone in your journey towards becoming a competent mechanical engineer. You probably know by now that the word "engineer" comes from the same root as "ingenuity." Engineers are the people who create (design) new objects that take humanity forward.
In your first year you were introduced to what it means to be a creative engineer. You were then taughtﾠthe scientific foundationﾠfor engineering design, and laterﾠhow things get fabricated, which is, of course, important because what you design must be manufacturable. In this course, you will learn how to design, size, and select the basic elements of machines: beams, columns, power transmission shafts, gears, keys and keyways, splines, seals, bearings, bolts and bolted joints, welds, andﾠwelded joints. You will learn how these elements may fail and how to design them so that they will not fail.
The design tasks in this course will be well-defined and the solutions will not be totally open-ended.ﾠOur priority in this course is to make you become competent with the methods of rigorous analysis. You will demonstrate your competence in the assessment: quizzes, two design projects, and aﾠfinal examination.
