__Abstractions: Symbolic, Graphical, and
Geometrical
Representions Assignment__

MECC192 Homework Assignment

**Due October 10 at 5 p.m.**

Fall 2003

** Assignment Objective:**
Using various kinds of abstractions and representations, this exercise
is to (1) envision, (2) graphically represent, and (3) produce a 3D
form.

** Solution Requirements:**
The solution must meet the requirements of being a single, solid object
that will pass all the way through each hole of the mating block while
filling all three holes edge to edge and corner to corner.

** Mating Block Description:**
A solid rectilinear block which has been pierced with a circular,
triangular,
and square holes. The circle's diameter, the triangle's altitude
and base, and the square's sides all have the same unit
dimension.
The walls of the three holes are perpendicular to the flat front face
(or
plane) of the block.

** Process to Follow: **
Envision a working solution to the problem described above. Make
sketches and seek a graphical representation of the solution.
Consciously
interate between envisioning a solution and making sketches of possible
solutions. Critically analyze your possible solutions until you
find
an elegant solution. Finally, create a 3-D model of your solution.

** Ideas to Get Started:
**You can simulate
the
pierced block by making a cardboard or posterboard cut-out. Using
scissors or Exacto knife and the poster/cardboard materials, create
prototype
solutions by actual "cut-and-try" prototyping methods.

** To Hand In:**
Please
hand in a (1) final sketch, (2) your mating block and (3) 3-D shape you
have fabricated that solves the design problem. Be sure your name
is on all three.

** Due Date:**
Friday, October 10 at 5 p.m. to the MECC192 box located inside the ME
office.
