Street photography is photography that features the chance encounters and random accidents within public places.
Street photography does not necessitate the presence of a street or even the urban environment. Though people usually feature directly, street photography might be absent of people and can be an object or environment where the image projects a decidedly human character in facsimile or aesthetic.
Framing and timing
Framing and timing can be key aspects of the craft with the aim of some street photography being to create images at a decisive or poignant moment. Street photography can focus on emotions displayed, thereby also recording people's history from an emotional point of view.

Suspension Bridges - Design Technology
Suspension bridges in their simplest form were originally made from rope and wood.
Modern suspension bridges use a box section roadway supported by high tensile
In the early nineteenth century, suspension bridges used iron chains for cables. The
high tensile cables used in most modern suspension
bridges were introduced in the late nineteenth century.
Today, the cables are made of thousands of individual steel wires bound tightly together. Steel, which is very strong under tension, is an ideal material for cables; a single steel wire, only 0.1 inch thick, can support over half a ton without breaking.
Light, and strong, suspension bridges can span distances from 2,000 to 7,000 feet far longer than any other kind of bridge. They are ideal for covering busy waterways.
With any bridge project the choice of materials and form usually comes down to cost. Suspension bridges tend to be the most expensive to build. A suspension bridge suspends the roadway from huge main cables, which extend from one end of the bridge to the other. These cables rest on top of high towers and have to be securely anchored into the bank at either end of the bridge. The towers enable the main cables to be draped over long distances. Most of the weight or load of the bridge is transferred by the cables to the anchorage systems. These are imbedded in either solid rock or huge concrete blocks. Inside the anchorages, the cables are spread over a large area to evenly distribute the load and to prevent the cables from breaking free.
The Arthashastra of Kautilya mentions the construction of dams and bridges.A Mauryan bridge near Girnar was surveyed by James Princep. The bridge was swept away during a flood, and later repaired by Puspagupta, the chief architect of emperor Chandragupta I. The bridge also fell under the care of the Yavana Tushaspa, and the Satrap Rudra Daman. The use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India.
