The primary purpose of a bridge is to enable the safe and efficient movement of people and goods across a physical barrier, such as a river, valley, or road.

Truss bridges are not a common type of bridge. They are typically used for shorter spans and are less efficient than other types of bridges.

Girders are the main load-bearing elements in a beam bridge. They are typically made of steel or concrete and are designed to carry the weight of the bridge deck and traffic.

Suspension bridges are known for their long, slender decks supported by cables. These cables are typically made of steel and are designed to carry the weight of the bridge deck and traffic.

Piers are used to provide a foundation for the bridge. They are typically made of concrete or steel and are designed to transfer the weight of the bridge deck and traffic to the ground.

Glass is not a common material used in bridge construction. It is typically used for aesthetic purposes, such as in the windows of a bridge.

Weathering, erosion, and corrosion are all terms used to describe the gradual deterioration of a bridge due to environmental factors.

Destructive testing is not a common type of bridge inspection. It is typically only used when a bridge is suspected of being unsafe.

Bridge expansion joints serve multiple purposes, including allowing for expansion and contraction of the bridge deck, providing a smooth transition between different sections of the bridge, and preventing water from leaking into the bridge deck.

Ball bearings are not a common type of bridge bearing. They are typically used in machinery and other mechanical applications.

Capacity is the term used to describe the maximum load that a bridge can safely carry. It is typically determined by calculating the sum of the live load and the dead load.

Scour is not a common type of bridge failure. It is typically caused by the erosion of the soil around the bridge piers.

Bridge pier caps serve multiple purposes, including distributing the load from the bridge deck to the piers, providing a level surface for the bridge deck to rest on, and protecting the piers from weathering and erosion.

Diaphragm abutments are not a common type of bridge abutment. They are typically used for bridges with short spans.

Lateral load is the term used to describe the horizontal force that a bridge must resist due to wind or seismic activity.
