A plane frame is made from fully welded hollow square section steel members making a 45° truss. The truss has special end mountings supplied that allow different end bearing conditions to be used, i.e. pinned and roller end. The end mountings also allow the frame to be inverted for work on an inverted truss. Seven members of the truss are strain gauged with half bridge arrangements. Each strain gauge pairing has a cable loom attached and terminated with a numbered connector. This connector can be fitted into the optionally available HPM15 Data Acquisition Interface for direct reading of the member strain during loading. The truss has been specially designed to be tested in the HPM1 MAGNUS Test frame. The HPM2 standard accessories supplied with the HPM1 are required. The experiment calls for joint deflections to be measured during testing. Safety chains and high level reaction supports are supplied with this apparatus.
Essential accessories: HPM1, HPM3 or HPM3a
