摘要

Figure 12 (page 15) shows the basic classroom setup used for testing trusses. The setup consists of 2 C-clamps, locking pliers, a 5-gallon bucket where sand or gravel weight is added, and two classroom tables set up parallel to each other-in this case 9 inches apart. After the truss fails, a luggage scale is used to measure the combined weight of the locking pliers, bucket, and sand or gravel. Designing, constructing, and testing trusses is a useful activity that connects science and math learning with application in a technology and engineering classroom.
