Suspension bridge Dynamic load refers to environmental factors that go beyond normal weather conditions, factors such as sudden gusts of wind and earthquakes. All three factors must be taken into consideration when building a bridge. The principles of suspension used on the large scale may also appear in contexts less dramatic than road or rail bridges. Light cable suspension may prove less expensive and seem more elegant for a cycle or footbridge than strong girder supports. An example of this is the Nescio Bridge in the Netherlands. Where such a bridge spans a gap between two buildings, there is no need to
Suspension (vehicle) Mini. A number of different types of each have been used: Traditional springs and dampers are referred to as passive suspensions — most vehicles are suspended in this manner. The majority of land vehicles are suspended by steel springs, of these types: Automakers are aware of the inherent limitations of steel springs, that they tend to produce undesirable oscillations, and have developed other types of suspension materials and mechanisms in attempts to improve performance: The shock absorbers damp out the (otherwise simple harmonic) motions of a vehicle up and down on its springs. They also must damp out much of
