HARDWARE
The experiment hardware fits onto the Structures Test Frame (STR1, available separately). 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.

VIRTUAL EXPERIMENTS
The Simple Suspension Bridge Experiments Software enables computer simulation of experiments working with or without the Structures teaching hardware. As well as all the experiments possible with the hardware, the software extends investigations further. For example: using higher loads, uniform loads or different test specimens
During experiments, the software displays a force diagram. Students can visualise, tabulate and graph data, reducing the time required for students to obtain, process and present results. This allows students to realistically, efficiently and conveniently investigate the characteristics of a simple suspension bridge.
The Virtual Experiments Software is available in a variety of multi-user and networked options, as well as single-user format.
