ELEMENTS OF DESIGN

(Mr. Gilet)

A course of one lecture and two hours' drawing office work per week commencing in the seventh week of first term.

The purpose of this subject is to serve as an introduction to the course in Engineering Design in the third year. It covers the general approach and other factors relevant to simple design problems and the preparation of engineering drawings.

SYLLABUS. General approach to design problems, methods of investigation for design, appropriate accuracy, and preparation of engineering drawings.

Manufacturing processes and their influence on design.

The use of first principles in the design of machine elements.

Working stresses and factors of safety, the use of standard specifications and codes.
