Introduction
The PASCO model ME-6988A Force Platform Structures
Bracket includes two brackets and four thumbscrews. The
adapter bracket is designed to connect members of the PASCO
Structures System to a PASCO Force Platform.
Each Force Platform Structures Bracket has six positions where
members of a PASCO Structure System can be attached, and two
thumbscrews for attaching the bracket to a Force Platform. Note
that each bracket also has two threaded holes for storing the
thumbscrews when they are not in use.
Examples of the PASCO Structures System include:
Truss Set (ME-6990) - A small set for building trusses
Bridge Set (ME-6991) - A larger set with road bed and
cables for building bridges and roller coasters
Advanced Set (ME-6992A) - The largest set with pulleys,
axles, and additional connectors that make possible bridges
which have angles other than 45 and 90 degrees. This set can
also be used to build suspension bridges, cranes, cars and
catapults.

The Structures System also includes sensors for measuring forces
in a structure.
Load Cell and Amplifier Set (PS-2199) - Load Cell Ampli-
fier (PS-2198) with four 100 N Load Cells (PS-2200)
Load Cell Amplifier (PS-2198) - Can plug in up to six Load
Cells; requires a PASPORT interface to connect to the USB
port of a computer.
100 N Load Cell (PS-2200) or 5 N Load Cell (PS-2201) -
Strain gauges mounted on a beam with no electronics so a
Load Cell requires the Load Cell Amplifier (PS-2198).
The Force Platform allows the student to measure tension and
compression forces in trusses, bridges, roller coasters, or other
structures assembled with the PASCO Structures System sets.
See the PASCO catalog or web site (www.PASCO.com) for
more information about the PASCO Structures System.
Installation
Use two thumbscrews to mount a bracket to one side of a PASCO
Force Platform. Note that two brackets will fit on one Force Plat-
form.
Use Truss Set thumbscrews (ME-6994) from one of the PASCO
Structures Systems sets to attach I-beams or other members of a
structure set to the six attachment positions on the bracket. (See
Figure 1.)
Using Brackets on a Force
Platform
If a structure is connected to one or two Force Platform Structure
Brackets that are mounted on a Force Platform, the dynamic
changes in tension or compression of the members of the struc-
ture can be measured.
The different attachment positions along the side of the bracket
allow different I-beam members to be used between two Brackets
mounted on a Force Platform. Let the span of a structure be the
distance between its attachment positions on two Brackets. Let
the separation of the structure be the distance between two verti-
cal members attached to the same Bracket.
The center attachment positions (labeled “3”) allow a span and
separation of a #3 I-beam member. The next two attachment posi-
tions relative to the center allow a span and separation of a #4
I-beam. (See Figure 2.)
Use the thumb-
screws to attach
the Bracket to a
Force Platform.

3
The outermost attachment positions relative to the center are
designed for a span of a #4 I-beam and a separation of a #5
I-beam if the Brackets are mounted on a PASCO Force Platform.
However, if the Brackets are mounted on another platform, or no
platform as shown in Figure 3, then the span can be longer or
shorter than a #4 I-beam.
Please refer to the instruction manuals for the PASCO Structures
System Sets for ideas of what structures can be built and attached
to the Force Platform Structures Bracket and a Force Platform.
Examples include large bridges and a tower crane.
Other Uses for the Bracket
You can use the Force Platform Structures Bracket on a different
force-measurement platform if you have the means to attach the
Bracket to your platform.
As shown in Figure 4, it is also possible to attach a structure to
just one Force Platform Structures Bracket.
The attachment positions on the Bracket are at the same height as
the top attachment position on a “half-round” connector (part of
the ME-6990 Truss Set).
