Description
The experiment hardware fits onto the Structures Test Frame. Students use masses on weight hangers to apply various loads to a rigid deck, joined to a parabolic cable via hangers. The suspension cable passes over pulleys at each end. One end is rigidly fixed. The other end connects to a mechanism bearing on a load cell. When connected to a Digital Force Display (STR1a, available separately), the load cell measures the cable tension. The equipment includes a signal cable to connect the load cell to a Digital Force Display (STR1a). The lecturer guide provides details of the equipment including sample experiment results. The student guide describes how to use the equipment and gives experiment procedures. For extra ‘virtual’ experiments, we can supply the optional Structures Software (STRS), for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware. They also extend the choice of tests beyond that available using only the hardware, for example: higher loads, uniform loads or different test specimens. This extends the student’s learning experience. For automatic data acquisition of your experiment results, we can supply the optional Automatic Data Acquisition Unit. Supplied as standard with the is Structures Software that displays and logs your experiment results and gives the extra virtual experiments.
Learning outcomes
Demonstration of the characteristics of a simple suspension bridge
Examination of the relationship between applied loads and the suspension cable tension
Observation of the stability of the structure
