Further Study
1. Repeat the torque calculation, but measure the lever arms from a different point
(for instance, one end of the channel). How does the net torque change?
2. Repeat the torque calculation for a point in the recorded data where the ball is on
the same side of both force sensors.
3. Repeat the entire experiment with the force sensors attached to the beam at dif-
ferent points.
4. Repeat the experiment, but press the zero buttons on the force sensors before
attaching the beam. Measure the mass of beam and include it in the force and
torque calculations.
5. Repeat the experiment with the beam mounted on three force sensors.
Equipment Notes
PASPORT Interfaces
The recommended PASPORT Force Sensors and Motion Sensor require a PASPORT
interface or interfaces with a total of three ports (or four ports if three force sensors
will be used). Multiple PASPORT interfaces in any combination can be used to make
up the required number of ports.
ScienceWorkshop Sensors
A ScienceWorkshop Motion Sensor (CI-6742) and Force Sensors (CI-6537 or
CI-6746) can be used instead of PASPORT sensors. Open the DataStudio configura-
tion file SW Force Distribution.ds for two force sensors or SW Force Distribution (3
force).ds for three force sensors.
• If you are using a ScienceWorkshop interface, connect the motion sensor to
Channels 1 and 2; connect the left force sensor to Channel A, the right force sen-
sor to Channel B, and the center force sensor (if used) to Channel C.
• If you are using a Digital Adapter (PS-2159) and Analog Adapters (PS-2158)
with ScienceWorkshop sensors, connect the adapters for the left, right, and center
force sensors to the PASPORT interface (or interfaces) in that order.
