UNIT FOR STUDYING FORCES IN AN OVERDETERMINATE TRUSS
TENDER SPECIFICATIONS
The unit includes:
Anodized aluminum frame.
10 bars made of stainless steel.
A longitudinally adjustable surplus bar. Length: 400-450 mm.
3 bars of 425 mm long.
6 bars of 300 mm long.
These bars can form several plane truss structures with different angles between bars.
Maximum bar force: 500 N.
Strain gauge to measure force on each bar.
Five node discs, two of them are used to hinge the truss structure to the frame of the unit.
A load application device with a force gauge mountable on different node discs. Range: -500 … 500 N, graduations: 10N. This device allows to
generate straight and inclined external force.
A fixture with a dial gauge, dial gauge measurement range: 0-20 mm.
Electronic console:
Strain gauge connectors.
Digital display for the strain gauges.
Selector for strain gauges.
Amplifier.
USB connector for the connection to the computer (PC).
Software to evaluate the measurement data.
Cables and accessories, for normal operation.
Manuals: This unit is supplied with the following manuals: Required services, Assembly and Installation, Starting-up, Security,
Maintenance
and Practices manual.

Electronic console: 300 x 190 x 130 mm. approx. (11.81 x 7.48 x 5.11 inches approx.) Weight: 2.5 Kg. approx. (5.51 pounds approx.).
EXERCISES AND PRACTICAL POSSIBILITIES
1.- Investigation of forces in a statically determinate single plane truss.
2.- Investigation of forces in a statically overdeterminate single plane truss.
3.- Measurement of bar forces in the different configurations of the single plane truss using strain gauges.
4.- Study of the distribution of forces in the statically determinate single plane truss.
5.- Study of the distribution of forces in the statically overdeterminate single plane truss (using a surplus bar).
6.- Study of the dependency of bar forces on the external force in the different configurations of the single plane truss with the direction of the force.
7.- Study of the dependency of the bar forces on the external force in the different configurations of the single plane truss with the magnitude of the
force.
8.- Study of the dependency of the bar forces on the external force in the different configurations of the single plane truss with the application point of
the force.
9.- Calculation of bar forces in the different configurations of the statically determinate and statically overdeterminate single plane truss by Ritter's
method of sections.
10.-Calculation of bar forces in the different configurations of the statically determinate and statically overdeterminate single plane truss by the method
of joints.
11.-Comparison of the experimental bar forces with Ritter's method of sections and the method of joints in the different configurations of the statically
determinate and statically overdeterminate single plane truss.
Optional:
- MFCS2/CAI. Computer Aided Instruction Software System:
This complete software package consists of an Instructor Software (INS/SOF) totally integrated with the Student Software (MFCS2/SOF). Both are
interconnected so that the teacher knows at any moment what is the theoretical and practical knowledge of the students.
INS/SOF. Classroom Management Software (Instructor Software):
The Instructor can:
- Organize Students by Classes and Groups.
- Create easily new entries or delete them.
- Create data bases with student information.
- Analyze results and make statistical comparisons.

MFCS2
UNIT FOR STUDYING FORCES IN AN OVERDETERMINATE TRUSS
- Generate and print reports.
- Detect student’s progress and difficulties.
...and many other facilities.
This software, working in network configuration, allows controlling all the students in the classroom.
MFCS2/SOF. Computer Aided Instruction Software (Student Software):
It explains how to use the unit, run the experiments and what to do at any moment.
- This software contains:
Theory: gives the student the theoretical background for a total understanding of the studied subject.
Exercises: divided by thematic areas and chapters to check out that the theory has been understood.
Guided Practices: presents several practices to be done with the unit, showing how to perform the exercises and practices.
Exams: set of questions to test the obtained knowledge.
- MFCS2/CAL. Computer Aided Learning Software (Results Calculation and Analysis):
This Computer Aided Learning Software (Results Calculation and Analysis) “CAL” is a Windows based software, simple and very easy to use,
specifically developed by EDIBON.
CAL is a class assistant that helps in doing the necessary calculations to extract the right conclusions from data obtained during the experimental
practices. With a single click, CAL computes the value of all the variables involved and performs the calculations.
Also, CAL allows to plot and print the results. Within the plotting options, any variable can be represented against any other.
Available different plotting displays.
It has a wide range of information, such as constant values, unit conversion factors and integral and derivative tables.
