Quick Answer: The Pin-Jointed Frameworks experiment uses strain gauges, read through a strain gauge amplifier, to find the member forces in a roof truss under load. Load cells can apply angled loads, and an optional load cell adds a secondary load to the side of the truss.

Key Features
Strain gauges connect to a strain gauge amplifier and on to the USB interface hub of the Structures platform
Load cells can apply angled loads, including a simulated swaying load
Optional load cell for a secondary load on the side of the roof truss
About This Product
Students predict the member forces and deflections of the framework for a given load with textbook equations, then compare the predictions with the measured results. Educational Instrument can dispatch the Pin-Jointed Frameworks to laboratories in Italy, Afghanistan, Burkina Faso, Australia, Cyprus and Ecuador.
