Gate Bridge in San Francisco‚ United States Opened on 27 May 1937 and was the longest suspension bridge span in the world at the time. This remained until Verrazano Narrows Bridge was built in New York in 1964‚ Golden Gate Bridge is now the seventh longest main span in the world. Construction of the 8‚981 feet or 2‚737 m bridge commenced on January 5‚ 1933. The projected cost was $35 million‚ however it was completed at $1.3 million (in 1937) below the projected cost. The Golden Gate Bridge weighs

basic design was sound and the suspension bridge had been constructed competently. The project’s original plan and scope management may have been an appropriate one if it was for a shorter bridge. Since this bridge was so long The planners started taking unknown and unnecessary risks when they determined the width of the bridge would be single lane versus double and when they changed the girders from round to flat‚ preventing the wind to pass thru the bridge properly. When the location was chosen

Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law to determine the resistivity using the resistance of the wire‚ length of the wire‚ and cross sectional area. In order to relate a measured resistance as a function of length and obtain the value for an unknown resistor‚ a Wheatstone Bridge must be attached to a dc power supply‚ and a galvanometer. In order to

n architecture‚ a truss is a structure comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. External forces and reactions to those forces are considered to act only at the nodes and result in forces in the members which are either tensile or compressive forces. Moments (torques) are explicitly excluded because‚ and only because‚ all the joints in a truss are treated as revolutes. A planar truss is one where all the members

Abstract- The development of De-Sauty’s bridge for capacitance measurement has been followed by various modifications and improvements in the original circuit. Lately Schering bridge and transformer ratio arm bridge have been used for measurement of capacitance in a circuit.Today there is instrumentation available that makes use of these bridges in real life such as that can measure the quality of electrical insulation at power frequency as well as in touch-sensitive sensors.

Truss bridges are recognizable because of their numerous‚ relatively small interconnected triangles. This framework of triangles is used for is strength to withstand tension and compression forces. They are considered a light-weight yet a very stiff form of construction. At first they were built of wood‚ then with the discovery of welding they began to build then using iron‚ then steel. Occasionally‚ a combination of the materials may be used. There are actually 30 different kinds of truss bridges

Bridge On The River Kwai. The film deals with the situation of British and American prisoners of war‚ who were captured by the Japanese during World War II and were forced to build a bridge over the river Kwai‚ in order to accommodate Japanese Burma-Siam railway. At first the prisoners were planning to sabotage the construction of the bridge‚ and to not finish the construction at the scheduled date. Because of that decision‚ the Japanese were forcing British officers to be working along the ordinary
