Design Criteria: Physical requirements on which you base the design.

These requirements include objectives (ideal characteristics of the resulting
design) and constraints (characteristics that your design must satisfy)

selections
. This needs to include discussion of your specified performance
parameter selections.

(
e.g.,

)

and range for

).

ii. Solution(s) with final selections


You must include a figure

solution(s) with all
pin joints, link lengths, input angle, other link angles,
and CG’s

shown and
labeled exactly as in the equations u
sed in your analyses.


A good way to visually display the above is to make a table that
contains all the numerical values used placed directly below the figure. This
makes it easy for the reader to follow.
