  1. Do the process-related exercises.  Put the URL for your answers here:  
  2. 20# Xerox paper is about 100 microns thick. If you were to scale a sheet of Xerox paper down to 2 microns thick how big would it be?
  3. Given a single sheet of 20# Xerox copier paper and a 30 cm length of half inch wide Scotch tape, design a structure to support as many pennies as possible at least 40 cm above the surface of a flat, level, low-friction table top.

  4. You may:
      1. use scissors, razor blades, etc. to cut the paper and tape.
      2.  apply tape to the table top
      3.  choose how, when, and where the pennies will be placed on your design
      Not encouraged:
      1. Rolling the paper (tough to do with polysilicon).
      2.  Cutting separate pieces and assembling them later.
      Turn in a printout of your solution with solid lines where cuts are to be made, short dashed lines where the paper is to be folded up, long dashed lines where the paper is to be folded down, and outlines of tape attachment points. Attachment points should be numbered in order of suggested assembly, and with ``abc...'' markings to indicate which points are to be connected.

      Bring your solutions to class on the due date for a live competition after class. Your structure may be partly or completely assembled when you bring it, but you must be able to place it anywhere (without any additional supports).  In other words, you can't have it built and taped onto your own flat surface. Winning designs must carry the load for at least 10 seconds without collapse. Winners get a free lunch at the Northside Shops location of his/her choice.  You may work in teams of two.
