100 N Load Cell (PS-2200) - Strain gauges mounted on a beam with no electronics so a Load Cell requires a
Load Cell Amplifier (PS-2198) or Dual Load Cell Amplifier PS-2206).
5 N Load Cell (PS-2201) - Strain gauges mounted on a beam with no electronics so a Load Cell requires a Load
Cell Amplifier or Dual Load Cell Amplifier.
Displacement Sensor (PS-2205) - A PASPORT Sensor and a digital displacement indicator designed to measure
the deflection of parts of a structure such as a truss or a bridge.
Dual Load Cell Amplifier (PS-2206) - Can plug in one or two Load Cells; requires a PASPORT interface to
connect to the USB port of a computer.
About the Components
Beams
There are five sizes of plastic I-Beams, labeled #1 through #5. Beam #1 is the shortest beam. There are three
sizes of Flexible I-Beams labeled #3, #4, and #5, and three sizes of Flat Beams labeled 2 X 3, F4, and 3 X 4.
Assembling Beams
All beams attach to connectors in the same way. Use the included screws (6-32, slotted) to attach beams to a con-
nector (such as the half round connector) as illustrated.
Flexible I-Beams
Flexible I-Beams are the same size as the #3, #4, and #5 I-Beams, but they can be used to dramatically demon-
strate structure failure under a heavy load. The beams will return to their original shape when the load is
removed.

I-Beams
Flexible I-Beams are also
used in the construction of
suspension bridge models.
