In electronics, the Carey Foster bridge is a bridge circuit used to measure low resistances, or to measure small differences between two large resistances. It was invented by Carey Foster as a variant on the Wheatstone bridge.You may be familiar with the post office box and the meter bridge, which also
work on the same principle as Wheatstone s bridge. In the meter bridge, two of
the resistors, R and S, say, are replaced by a one meter length of resistance wire,
with uniform cross-sectional area fixed on a meter scale. Point D is an electri ....etc

An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passages. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few remotely usi ....etc

bridge bearing and stability ppt

Abstract

The designers of bridges must assure themselves that bridge bearings can transmit the high horizontal loads of current designs. The proportion of horizontal to vertical load is increasing due to the current trend toward continuous, joint free, redundant structures. From the 10 20% level of some years ago, horizontal forces are now found at and above the corresponding vertical loads. These horizontal forces require that bearing stability be investigated. Two levels of stability criteria, for normal c ....etc

Flyover vs Overbridge :

Flyovers, bridges, over bridges, underpasses, overpasses etc are some examples of engineering marvel that allow for saving of time and effort of people, vehicles, and even trains. Normally bridges are made over water bodies like rivers but over bridges are meant to provide a roadway for pedestrians and even vehicles over a railway line or even an under bridge. A flyover is a concept that allows roads to be built over roads to facilitate faster movement of people and vehicles in this age of congested traffic in metro c ....etc

MAIN PURPOSE:

The hydraulic jack is a device, which is used to lift heavy loads by applying a lot of small force. It is based on the PASCAL LAW, which states that the pressure intensity is equally transmitted in all directions through a mass of liquid in res
