Unit Description and General Aims

The objective in presenting this unit is to provide students with the fundamentals of design concepts including material selection; stress equations; loading types; failure theories; design methodologies based on strength and stiffness; and, design for different load conditions. Students will also be familiarized with various design codes and standards.

Additionally, the subject matter covered in this unit will include the background of basic dimensioning and visualization principles in engineering drawings; freehand sketching and drawing of basic geometrical constructions; and, an introduction to Computer Aided Drafting (CAD) packages and their applications, including a demonstration of their use. Students will also be instructed on developing their ability to visualize and communicate three-dimensional shapes, draw orthographic, and isometric projections and create 2D and 3D models using CAD.
