Interface and Software Setup
Connect the platform's cable to a PASPORT interface. A green LED on the side of the
platform lights to indicate that the unit is powered and ready to take data. Press the
tare button to set the output to zero.
Using the 2-Axis Force Platform with DataStudio
If you are using a computer, start DataStudio. Click the Start button to begin data col-
lection. By default, the platform collects data at 10 samples per second and displays it
in units of newtons (N). You can change these settings in the Experiment Setup win-
dow. (Click the Setup button to open the window.) In the Setup window you can also
make the separate force measurement of each beam visible. For more instructions on
using DataStudio, press F1 to open DataStudio's on-line help.
Using the 2-Axis Force Platform with the Xplorer GLX
If you are using an Xplorer GLX without a computer, press
to start data collec-
tion. By default, the platform collects data at 10 samples per second and displays it in
units of newtons (N). You can change these settings in the Sensors screen. (From the
Home screen, press
to open the Sensors screen.) In the Sensors screen you can
also make the separate force measurement of each beam visible. For more instruc-
tions on using the Xplorer GLX, refer to the GLX Users' Guide.
Safety
Teachers:
The 2-Axis Force Platform is designed for use by students under the supervision
of a teacher. Ensure that all users understand and follow these guidelines when jumping or
stepping on the platform.
•
Do not stand on or jump off tables, chairs, or other inappropriate objects.
•
Before you jump or step on the platform, be certain that it will not skid or move
and that you will land with your foot or feet entirely on the platform, not hanging
over the edge.
•
Use the platform away from objects that may interfere with your movements or
injure you if you fall.
•
Follow all other safety rules and guidelines that apply to you.
Suggested Activities
Walking
Place the platform on the floor. Starting several paces away, walk toward the platform
and step on it as you continue to walk forward. Study the vertical and horizontal
forces applied by your foot. In what direction does your foot apply force to the plat-
form in order to move you forward? In what direction does the platform apply force to
your foot? Repeat the exercise at different walking speeds. How does walking faster
affect the magnitudes of the horizontal and vertical forces?
