Bridges are primarily built to connect two points over a body of water, a valley, or any physical obstacle. Flyovers are constructed to navigate intersections, congested areas, or other roads efficiently, providing an elevated route for vehicles.

Difference Between Bridge And Flyover:

Bridge and Flyover can be differentiated depending upon their function, purpose of usage, and the location where it is built.

Differences:

Bridge:

1. The drainage structure which facilitates a communication route for carrying a road or railway traffic across an obstruction or depression with or without water is called a bridge.

2. Bridge is a structure that is built over natural obstructions such as rivers, valleys to connect two locations separated by these obstructions.

3. Bridges are further classified on the basis of their purpose, lifespan, materials, span, etc.

4. Bridges are used for navigating traffic across the obstruction, to navigate pipelines, and other forms of transport.

Flyovers:

1. Flyover is an overpass, a high-level road bridge that crosses over a highway interchange or intersection.

2. It is a structure that joins two or more points which are separated by accessible routes or a man-made structure to cut the traffic for a faster mode of travel.

3. They are usually made over road junctions, roads, streets, etc.

4. The name itself suggests that you are flying over a traffic zone.

5. They are usually built for road vehicles.

Anemometer is used to measure the wind speed. An anemometer looks like a weather vane, but instead of measuring the direction of wind with pointers, it has four cups so that it can accurately measure wind speed.

The most common type of anemometer has three or four cups attached to horizontal arms. The arms are attached to a vertical rod. As the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed. Because wind speeds are not consistent—there are gusts and lulls—wind speed is usually averaged over a short period of time.
