Stopwatch (ME-1234)
The PASCO Stopwatch has a liquid crystal dis-
play (LCD) with two display modes. Its precision
is 0.01 seconds up to 3599.99 seconds, and 1 sec-
ond up to 359999 seconds. Its memory holds up to
nine event times.
Mass Balance
Use a mass balance such as the OHAUS Scout
Pro Balance 2000 g (SE-8757A) or the OHAUS
Cent-O-Gram Balance (SE-8725).
Mounted Scale Assembly (ME-9824A)
The Mounted Scale Assembly (included in the ME-9505 Components Package) is also available separately as a
replacement or as an extra spring scale for experiments where measuring more than one force is required.
Spares Package (ME-9504)
The Spares Package contains some items which are used with assemblies from the Components Package. For
example, the String Tie Assembly snaps into the center of the Force Wheel Assembly and the Torque Indicator
Assembly snaps into the Torque Wheel Assembly. The Cord Tensioning Clip is used on the Utility Mount Assem-
bly. Other items such as the Angle Indicator Arms, thumbscrews, washers, and brass weight are replacement parts.
String Tie Assembly.
When the String Tie Assembly is snapped into the center of the Force
Wheel Assembly, you can use the apparatus to study force vectors. The
String Tie Assembly has two parts: a clear plastic inner part (the “force
disk”) that is free to move around in the center of the outer part, which
has a center hole and two tabs that snap into the Force Wheel Assembly.
(The two parts are not meant to be separated.)
Initial Setup
Get three threads that are 38 cm (15”) long. Put the threads through the
hole in the inner part of the String Tie Assembly. Tie the ends of the
threads together (for example, with an overhand knot) so that they cannot be pulled back through the inner part.
Torque Indicator Assembly
Note that the Torque Indicator Assembly has a
snap that can be connected to the Torque Wheel
Assembly. The other three assemblies are
spares.
Initial Setup
Tie a 30 cm (12”) thread to each of three Torque Indicator Assemblies.
