Technical Description
This training unit is used to investigate loaded plane trusses and enables the member forces to be measured. A pre-assembled main truss is included. The trusses are assembled using joint discs to avoid bending loading. Seven of the members are equipped with full bridge strain gauges for the measurement of force. A strain gauge connecting box is included in which the offset error of the individual strain gauges is already compensated. The FL 151 16-Channel Ext. Unit is recommended for measured signal conditioning. The loading device is mounted in bearings such that it can rotate, as a result it is also possible to apply forces at an angle. The unit is designed as an easy to operate table model. Further trusses are available as accessories, a laboratory trolley for storing the individual parts is also available.
Learning Objectives / Experiments
· Forces in a Howe main framework truss
