OBJECTIVES:

• To familiarise the various steps involved in the Design Process
• To understand the principles involved in evaluating the shape and dimensions of a component to satisfy functional and strength requirements.
• To learn to use standard practices and standard data.
• To learn to use catalogues and standard machine components (Use of P S G Design Data Book is permitted)
