Would it be possible to design a system, using a maximum of two 1 x 6 pine timbers (or the equivalent weight), that would span a total of eight (8) feet while supporting a 175-pound point load while succumbing to a maximum deflection of only one quarter (1/4) of an inch? Welcome to the first design-build project of the semester, lovingly titled the "Stress Test!"
So begins the semester, hope you enjoy our work.
These first images are of the two most successful designs. Be sure to scroll down and view all of the final design schemes and read about their levels of success.

Pictured in the photograph are: (Top Left) Meredith Hankins, Kerri Ingraham, Nelson Gomez, James Pfeiffer, as well as (Bottom Left) Christy Ketchel, and Matthew Bonner. ![]() Above: Group Photo Below: Christopher Jurgens measures the test heights, as Prof. Sagan prepares to "walk the plank!" (pun intended), or in this case, I-beam. ![]() Below: Prof. Sagan proves that surfing and design walk hand in hand. ![]() |
The following pictures highlight the other two groups design schemes and those who helped to create them.

Not pictured, but also a member of the group: Jeff Cooper. Below: Prof. Sagan, the 175 lb. point load, tests the groups design, although with some hesitation. This group's design managed to allow a maximum deflection of only 1/4 of an inch ![]() Below: The underside of the design reveals a web of tensioned cables helping to distribute the weight. ![]() |
These last two design schemes were created to further experiment with the given materials as well as to test other various ways of solving the problem.

And so ends the first project of the semester, with each group taking the lessons they have learned from this "experiment" and begining to think of ways to improve on their designs.
