Experiment: S2 – The Roof Truss Experiment
Aims: To gain practical experience of strain measurement using rain gauges, to compare experimentally determined forces in the roof truss with those predicted theoretically
Learning Outcomes
The evaluation of stresses and forces from experimental measurements of strain.
The determination of axial forces in the members of the roof truss with those predicted using method of joints.
Apparatus: Bench mounted model roof truss. Micrometer.
Procedure: The applied load was set to zero at joint A and measurements were taken of all the strain gauges on the roof truss model. The applied load on joint A was increased to 100N and measurements ...
