Structural Demonstration Models

• Self-contained model
• Immediate analogue solution
• Effective teaching aid
• Illustrates moment distribution coefficients
  and carry over
• For lecture or laboratory
• Three year warranty

Range of Experiments

1. Measurement of moment distribution coefficients for a remote end fixed and free
2. Measurement of carry over factor to a fixed end

The model is built on a pressed steel base with plastic piers that support a single span flexible steel beam on swivelling bearings which can accommodate horizontal movement while enabling external moments to be applied and measured. An inserted locking pin makes a fixed end. Rotation of the beam at the support is shown by a large coloured pointer moving across a dual scale, the coarse one being readily seen at 10 m distance. The set of weights needed for the experiment is included.

This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results.

A set of thick plates is supplied to enable a forced displacement to be produced at one end and the internal supports.

A complete instruction manual is provided describing the apparatus, its application, experimental procedure and theory. Although the equipment is designed primarily for use by lecturing staff, the manual has a section provided for individual student use.

• Cost effective teaching aid
• Enables seven models to be built
• Each model self contained
• Excellent introduction to the theory for redundant structures
• Three year warranty

See the individual experiments. All the parts to make the models are provided and the set of weights needed for the experiments is included. A complete set of Lecturer's Instruction Manuals and students laboratory sheets is supplied. There is also a Manual explaining the construction of each of the seven models.
