1st Semester of A.Y. 2016-2017.
WFY : ME 4 WF 16:00 –17:30.
course description and objectives
This course deals with the intricacies of designing machines. Machine elements such as gears, bolts, welds, springs, etc.
will be tackled in detail. Knowledge from a first course in machine design and engineering mechanics will be used
for the identification, selection, analysis, and design of machine elements. The ability to integrate machine structures
and elements in order to satisfy a certain need is the core competency required in machine design practice. As such, a
systematic mechanical design process will be taught early in the course so students can start embracing design thinking
and philosophy while doing subsequent course and life requirements. This course aims to:
· Provide students with the knowledge of different machine elements and all of their design parameters and characteristics.
· Further hone students’ engineering design abilities.
· Foster teamwork, comradeship, and professional behavior among students through projects involving the creation
of valid and acceptable engineering designs.
· Motivate students to use all knowledge accumulated from all past courses on engineering mechanics and machine
design in creating machines.
· Let students apply their solid modeling and drafting skills in producing engineering drawings of machines.
· Ensure students can apply all the aforementioned knowledge and skills in designing functional, safe, and sufficiently long-lasting engineering products.
learning outcomes
