Bridge Knowledge Quiz

What is the main purpose of a bridge?

• To allow people and vehicles to cross over an open space

• To decorate the landscape

• To block rivers

• To create a playground

Answer explanation

The main purpose of a bridge is to allow people and vehicles to cross over an open space, such as a river or a road, facilitating transportation and connectivity.

Which type of bridge is the oldest and simplest?

• Beam bridge

• Suspension bridge

• Arch bridge

• Cable-stayed bridge

Answer explanation

The beam bridge is the oldest and simplest type of bridge, consisting of horizontal beams supported at each end. Its straightforward design makes it easy to construct and understand, distinguishing it from more complex bridge types.

What material is NOT commonly used to make bridges?

• Plastic

• Wood

• Iron

• Concrete

Answer explanation

Plastic is not commonly used to make bridges due to its lack of strength and durability compared to materials like wood, iron, and concrete, which are standard in bridge construction.

What is a clapper bridge made from?

• Long, thin slabs of stone

• Metal beams

• Wooden planks

• Concrete blocks

Answer explanation

A clapper bridge is traditionally constructed using long, thin slabs of stone, which are laid across a river or stream. This design allows for stability and durability, making it the correct choice compared to other materials.

What is reinforced concrete made by setting?

• Steel bars in concrete

• Wooden beams in stone

• Iron rods in sand

• Plastic pipes in gravel

Answer explanation

Reinforced concrete is made by embedding steel bars in concrete. This combination enhances the tensile strength of concrete, making it more durable and suitable for construction, unlike the other options listed.

Which type of bridge is known for its ability to span long distances with minimal support?

• Arch bridge

• Beam bridge

• Suspension bridge

• Truss bridge

Answer explanation

A suspension bridge is designed to span long distances by using cables to support the deck, allowing for fewer supports compared to other types like arch or beam bridges, making it ideal for large spans.

Which of the following is a key advantage of using steel in bridge construction?

• Lightweight

• Low cost

• Easy to carve

• High tensile strength

Answer explanation

The key advantage of using steel in bridge construction is its high tensile strength, which allows it to withstand significant forces and loads, making it ideal for supporting large structures.
