The experiment hardware fits onto a Multi Structures Test Frame (ASTR1, available separately). Students rest a beam on up to three ‘piers’. The piers are movable, so students can arrange them in many different positions under the beam. Students use masses on weight hangers to load the beam. They can also attach the flexible beam to a backboard to measure deflection or fixing moment.
The piers each contain a load cell to measure vertical reactions. These connect to a Multi- Channel Digital Transducer Display (ASTR1 a, available separately). Two of the load cells have knife-edge supports, which students can either fix or allow to sink by a set displacement. The third pier load cell allows students to either clamp the beam (encastré fixing) or rest the beam on a knife edge. The unique design of this equipment allows the load cell to resist the bending moment while accurately measuring the vertical reaction. To measure beam deflection, the backboard has a digital indicator which students move along the beam. The backboard also has a mechanism for measuring the fixing moment of a propped cantilever or a fixed beam.
