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.
