Strength Testing of Four Variations of the Warren Truss

The purpose of our experiment was to see which variation of the warren type truss (the basic warren, warren with supports, subdivided warren, and angular warren type truss) was able to withstand the most amount of weight through a single truss. After constructing a truss, it would be placed into the truss testing device, all the while fitted around a door hinge which is connected to a string. A bucket is fastened to the opposite end of the string and is filled with sand until the truss breaks completely. After collecting all our data, we analyzed the results using visual analysis, which consists of several graphs and averages. Our results showed that our hypothesis was proven incorrect with the angular type truss only holding an average of 8.26 kg. The basic warren held 6.13 kg on average, the warren with supports averaged 7.67 kg, while the subdivided held 8.32 kg on average, making it the best out of the four variations of the warren truss based upon the average. Consistency, however, was most prevalent in the angular type truss, due to the vastly varying weights in each of the remaining three types of trusses.
