Experiment Tips
a) To add the free mass, lay the components over the attachment screw in
the following order: a) cable b) mass and c) thumbscrew to tighten.
(Note: Place the cable over the washer and nut on the screw. For more
details, see “Equipment Setup” on pages 5-7.)
Note: Do not place the mass underneath the cable, as this will
interfere with a proper measurement.
b) Allow the “free mass” plenty of length along its holder within the
slot. If the mass is not free to slide along the groove, significant
frictional losses can be present.
c) Place an equal amount of mass on the “fixed mass” and “free mass”
holders.
d) Be sure to place the “fixed mass” at the same radius as the “free
mass” to ensure balancing of the unit at is rotates.
e) The velocity of the free mass can be measured as an angular or
linear velocity. DataStudio files for both of these variations are
included on the floppy disk.
f) Be sure to enter the correct value for the radius in the experimental
constants area of the calculator (when using the linear velocity
DataStudio file).
