Simple Suspension Bridge

Laboratory: 
Mechanics of Materials Lab
Simple Suspension Bridge

Range of Experiments

  • Comparison of simplified theory with experimental results for a uniformly distributed load
  • Study of the effect of a moving point load

Description

A rigid bridge deck is carried each side by hangers of different lengths such that the flexible steel cables from which they hang are constrained to a parabolic curve. The twin suspension cables pass over pulleys each end of the 1 m span and terminate in yokes carrying load hangers. Adjustable stops prevent the yokes moving upward and mark the correct length from the cables. Steel bars are provided to simulate a uniformly distributed load, and a special point load is supplied. The set of weights needed for the experiment is included. Software is accessible for processing results.

This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught.
