Description and Specification for Lab Tenders
Astra Scientific Pin Join Truss Apparatus Data Acquisition.
Description:
An experimental apparatus to create a wide selection of pin-jointed frameworks and then investigate the effects resulting from applying loading forces to them.
The experiment hardware fitted a Structures Test Frame. Students use stainless-steel members to build different pin-jointed frameworks. The members join by slotting the ends into bosses.
The equipment includes two framework supports: a pivoting support, and a pivoting and rolling support. Each member has a strain gauge attached that connects to a digital strain bridge. A load cell applies loads to the structure at various angles. When connected to the optional Digital Force Display, the load cell measures the applied load. To apply loads simultaneously, extra load cells are available.
A digital deflection indicator measures the deflection and the digital strain bridge shows the strains in the members. From this, students can calculate the forces in the members.
supplies the members in a custom-made storage tray to avoid accidental damage. A second tray stores the joint bosses and other loose items.
