The experiment hardware fits onto a Multi Structures Test Frame (ASTR1, available separately). Students apply various loads at set positions along the top of a simple ‘determinate’ threepinned arched structure. They can also apply a uniformly distributed load.
The structure has a pivot at one end and at the crown. The arch rolls against a load cell at the opposite end. The load cell connects to a Multi-Channel Digital Transducer Display (ASTR1a, available separately) to measure and display the thrust reaction. The equipment includes a lead to connect the load cell to a Multi-Channel Digital Transducer Display (ASTR1 a).
