Abstract

The purpose of this experiment was to find which truss deign could support the most mass. To carry out the experiment, four trusses were built. These trusses were built of balsa. All of the trusses we elevated on either side then mass was applied to the trusses until they broke. The mass was measured in grams. After the experiment was carried out, the control held an average of 1513.8 grams. The Warren truss held an average of 3777.2 grams, 249% of the control. The Pratt truss held an average of 3983.95 grams, 263% of the control. The Baltimore truss held an average of 5480.4 grams, 362% of the control.
