For each component, show its location within the structure and consider possible loading scenarios. Construct a Model for each loading scenario. For each model, draw a Free-Body Diagram and do Analysis. Then make a Decision. Two team members must sign off for each Decision. The Model displays either the component removed from the structure or the structure itself, with boundary supports. Free-Body Diagrams must be drawn even in simple circumstances. Analysis is used to determine dimensions or check critical stresses and deformations. The Decision sets final nominal dimensions and other conclusions; if it is not obvious, give reasons for it. Title each calculation set by Component Name. Sets of calculations should follow a logical sequence. Avoid over-design. Seek a "tight" design near the feasibility limit. Design formulas transformed from conventional analysis formulas should be developed; spreadsheet analysis should be clearly described and a sample hand calculation shown.
