Bridges Design Test

What is the maximum span length a Beam bridge can achieve?

• 360 feet

• 800 feet

• 250 feet

• 7,000 feet

Truss bridges utilize which geometric shape to distribute forces?

• Circles

• Triangles

• Squares

• Arches

What is the fundamental difference between tension and compression?

• Tension is a pushing force, while compression is a pulling force.

• Tension shortens the object, while compression lengthens it.

• Tension is a pulling force, while compression is a pushing force.

• There is no difference; they are the same force.

Which type of bridge can span the greatest length?

• Beam bridge

• Truss bridge

• Arch bridge

• Suspension bridge

Arch bridges are particularly strong due to their shape. What does the arch do?

• It concentrates tension at a single point.

• It distributes tension onto the abutments.

• It distributes compression onto the deck.

• It spreads out the forces of tension and compression onto the abutments.

What is torsion?

• A force that occurs when two opposing forces act on the same point

• A twisting force applied to an object

• The length of the bridge from one pier to another

• The surface of a bridge where vehicles travel

What is the role of abutments in a bridge?

• To serve as the surface where vehicles travel

• To act as a long, rigid vertical support part of the structure

• To absorb forces placed on the bridge and prevent the earth under the approach from moving

• To span vast areas

What is an arch in the context of bridge construction?

• The length of the bridge from one pier to another

• A curved structure that spans an open space

• The foundation that connects the structure to the earth

• A part of the structure frame based on the geometry of the strength of the triangle

What is the purpose of a bridge's deck?

• To absorb many of the forces placed on the bridge

• To span vast areas

• To be the surface where vehicles travel

• To connect the structure to the earth and transfer loads

What does the term "span" refer to in bridge terminology?

• The twisting force applied to the bridge

• The vertical support part of the structure

• The length of the bridge from one pier to another

• The surface of a bridge where vehicles travel
