Range of Experiments
- Comparison of experimental results of beam reactions with theoretical values from equations of equilibrium
- Addition of sets of results for several loads to illustrate superposition
- Wall reaction and fixing for a cantilever
Description
Two weighing machines of 50 N capacity with knife edge supports instead of scale pans are set on a base providing a span up to 1 m to show the end reactions when various loads are hung on the beam. Three load hangers permit a build up of load to be applied. The alternative support system for the cantilever is one weighing machine and a spring balance to develop the fixing moment and wall reaction. The cantilever is kept level by an adjustable fastening on the spring balance. The set of weights needed for the experiment is included. Software is accessible for processing results.
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. 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.
