The 45° two bay truss consists of seven members with pinned joints cantilevered from the vertical member of the HST1 Universal Frame and Stand (sold separately) using an upper springing and supported by a roller bearing on a vertical track at the lower springing. An extra diagonal member with its length adjustable by a simple mechanism is provided to make the first bay of the truss redundant.
Each truss member incorporates a strain gauge bridge arrangement for direct measurement of strain. Load is applied to the truss by a screw jack mechanism with integral load cell. The strain and force signals are fed directly into the HDA200 Interface (sold separately). A dial gauge measures the deflection of the joints and can be located around the truss from the HST1 Universal Frame and Stand (sold separately).
A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
