Range of Experiments
- To compare experimental results with the member forces calculated by resolution of the forces at joints
Description
A wall mounted plane frame built of six twinned members of Perspex has all joints pinned for direct comparison with theory.
The 45º cantilever truss has two bays of 400 mm with a load hanger at the outer end. Forces in the members are measured by a clamp-on electronic strain gauged transducer with a meter that reads out in Newtons up to 300 N full scales. 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.
