Students use masses on weight hangers to apply various loads to a rigid deck, Essential Ancillary joined to a parabolic cable via hangers. • Digital Force Display (STR1a) The suspension cable passes over pulleys at each end. One end is rigidly fi xed. The other end connects to a Recommended Ancillary mechanism bearing on a load cell. When connected to • Automatic Data Acquisition Unit (STR2000) for a Digital Force Display (STR1a, available separately), the automatic data acquisition and virtual experiments load cell measures the cable tension. The equipment includes a signal cable to connect the load cell to a Digital Operating Conditions Force Display (STR1a). Operating environment: The lecturer guide provides details of the equipment Laboratory including sample experiment results. The student guide describes how to use the equipment and gives experiment Storage temperature range: procedures. –25°C to +55°C (when packed for transport) For extra ‘virtual’ experiments, TecQuipment can supply Operating temperature range: the optional TecQuipment Structures Software (STRS), +5°C to +40°C for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware. Operating relative humidity range: They also extend the choice of tests beyond that available 80% at temperatures < 31°C decreasing linearly to 50% at using only the hardware, for example: higher loads, 40°C uniform loads or diff erent test specimens. This extends the student’s learning experience. Detailed Specifications For automatic data acquisition of your experiment results, TecQuipment is committed to a programme of continuous TecQuipment can supply the optional Automatic Data improvement; hence we reserve the right to alter the Acquisition Unit (STR2000). Supplied as standard with design and product specifcation without prior notice. the STR2000 is TecQuipment’s Structures Software that Nett dimensions and weight: displays and logs your experiment results and gives the extra virtual experiments. 700 x 310 x 70 mm and 4.5 kg Packed dimensions and weight: Standard Features Approximately 0.078 m3 and 6 kg • Supplied with lecturer guide and student guide Loads: • Five-year warranty 9 weight hangers and 150 x 10 g masses • Made in accordance with the latest European Union Cable: directives 100 mm sag, 500 mm span • ISO9001 certifi ed manufacturer Accessories: Rule 310 mm 700 mm TecQuipment Ltd, Bonsall Street, long eaton, Nottingham NG10 2AN, UK tecquipment.com +44 115 972 2611 [email protected] PE/db 1119 Page 2 of 2.
