Pin Jointed Frameworks Apparatus

Product Description

Description of Pin Jointed Frameworks Apparatus

The Pin Jointed Frameworks Apparatus enables students to assemble two Pin-Jointed Frameworks (warren and basic roof truss) to measure the strains (hence stresses) and joint deflections. Each member of the framework can be easily interconnected with each other by use of simple joints that are designed to create a truly pin joint.

The Pin Jointed Frameworks Apparatus mount onto two end supports. One support has a pivoting arrangement whilst the other has pivoting and rolling arrangement. The loads on the Pin Jointed Frameworks Apparatus are applied at known joints by using the screwjack loading mechanism supplied. Each framework member has a strain gauge arrangement attached. The signal from the loading mechanism and strain gauges is fed directly into the Interface
