The trainer investigates the measurements of the bar forces in a single plane truss (ST106) The construction of various trusses forms can be implemented. The trainer is equipped with bars with strain gauge measurement to measure bar force.

  • The Forces in various single plane trusses training system consists of the forces in various single plane trusses kit and the weights kit.
  • The training system aims to measure the bar forces in a single plane truss subjected to a single external force.
  • The training system studies trusses (bar structures) in which the bars are subjected to compression or tension loading, but not to bending.
  • The bars in this trainer are bars with special snap-lock closures on their ends allowing them to be fixed easily into the node disk.
  • The training system includes a range of different bar lengths to permit three statically determinate trusses to be constructed.
  • The bars are hinged, joined together by node disks, and are subjected only to compressive or tensile stress. No moments are transmitted in the nodes; they can be regarded as frictionless.
  • Consequently, the trusses can be considered as ideal trusses. A load application device attached to a node disk generates an external force.
  • strain gauges are provided for the measuring and recording of all the forces on the truss bars.
  • Computerized evaluation of the measured values required for measuring amplifier (16 input channels) (not included).
  • The software in the amplifier is used to manage the measured data and provide graphical representation of the bar forces (not included).
  • All the component elements of the experiment are clearly laid-out and housed securely in a storage system.
  • The complete experimental can be setup on the mounting frame.
