Due to the mechanical arrangement, there must always be a net downward load on the longer side of the split beam. The beam is simply supported on end bearings and several weight hangers can be attached at any position on either side of the joint. A hinged metal strip is available to simulate the loading pattern of a panelled girder for a more advanced experiment on influence lines. 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..
