What is a bridge in physics?
A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are “bridged” by a third branch connected between the first two branches at some intermediate point along them.

How do bridge works?
Bridges are able to carry greater loads and cover longer spans when they balance the forces exerted on them from their own mass and from that of anything that is placed on them. These forces tend to be compression, when the bridge is squeezed, and tension, which stretches the bridge.
What forces are acting on the bridge?
Two major forces act on a bridge at any given time: compression and tension. Compression, or compressive force, is a force that acts to compress or shorten the thing it is acting on. Tension, or tensile force, is a force that acts to expand or lengthen the thing it is acting on.
What forces act on a bridge?
How bridge is constructed in sea?
When bridges requiring piers are built over a body of water, foundations are made by sinking caissons into the riverbed and filling them with concrete. Caissons are large boxes or cylinders that have been made from wood, metal, or concrete. In the case of suspension bridges, towers are built atop the caissons.
How does gravity work on a bridge?
Gravity has the most profound impact on a bridge. Gravity is a constant – no matter what the other conditions, gravity is always acting on a structure, trying to pull it down. Bridges are at an even more unfair advantage against gravity since they span open spaces.
How do bridges expand?
Bridges expand and contract thanks to thermal expansion and contraction. The former increases a material’s volume, and the latter shrinks it. Both happen due to temperature changes. Bridges have expansion joints built, so movement from thermal differentials doesn’t damage them.
What science is used to build bridges?
There are a lot of things to consider when designing a bridge. Physics is a field of science that studies matter, energy, forces, and more. People who design bridges need to understand some important physics concepts in order to make a bridge that will be strong, stable, and secure over time.
How are bridges designed in physics?
In general, bridges are designed by two different types of people. Architects are responsible for how a bridge looks while engineers are responsible for how the bridge works and is supported. There are a lot of things to consider when designing a bridge. Physics is a field of science that studies matter, energy, forces, and more.
What is bridge design and construction?
Although the concept itself is as simple as felling a tree across a creek, bridge design and construction entails serious ingenuity. Artists, architects and engineers pour vast resources into bridge construction and, in doing so, reshape the very environment in which we live.
What are bridges made of?
We’ve tamed steel, stone, lumber and even living vegetation, all in an effort to reach the places, people and things we desire. Although the concept itself is as simple as felling a tree across a creek, bridge design and construction entails serious ingenuity.
