Go Direct® Structures & Materials Tester


Using our Go Direct® Structures & Materials Tester and its included e-book, students explore the effect that beam dimensions and shape have on structure flexibility and strength, investigate how trusses distribute weight, and ultimately build and test their own designs. For more advanced investigations, students can combine the sensor displacement data to evaluate the strengths of materials by determining the modulus of elasticity of different materials. This testing apparatus gives teachers a great way to motivate their students when it is used for engineering competitions with the free Go Direct® Bridge Competition Software.


  • The force and displacement sensors connect via Bluetooth® wireless technology or USB.
  • Uses our free Graphical Analysis™ 4 app to collect and analyze data.
  • Obtains exact force and displacement readings for bends and breaks.
  • Provides accurate positioning for center and off-center loading.
  • Accommodates easy loading for different structure sizes and shapes.

Includes the NGSS-aligned Materials Testing: Beams to Bridges e-book, providing engaging engineering activities to get started.
