A computer interface unit and software are included. The Simple Suspension Bridge Computer Interface set has the same accessories as except Vertical Load Cell is used instead of load hanger and weights.
....
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. 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 equipment includes a signal cable to connect the load cell to a Digital Force Display). When connected to a Digital Force Display, the load cell measures the cable tension.
Experiments:
Examination of the relationship between applied loads and the suspension cable tension
Demonstration of the characteristics of a simple suspension bridge
Comparison of behaviour to simplified cable theory
Observation of the stability of the structure.
