ME180 Lab Final Project Spring 2008
Project:
Organize into groups of 4 students each (from same lab section. Some groups may need to consist of 3 members). Disassemble physical product assembly given to each group and determine approximate dimensions
The Design Process
The design process involves organizing the creative and analytical processes used to satisfy a need or solve a problem. Sketches, drawings, computer models, and presentation graphics are all linked to the design and production p
