What is unique about Da Vinci's self-supporting bridge?

• It uses permanent joints.

• It is made entirely of metal.

• It becomes stronger with more weight.

• It requires nails and glue.

Answer explanation

Da Vinci's self-supporting bridge is unique because it becomes stronger with more weight, allowing it to distribute forces effectively, unlike traditional bridges that may weaken under heavy loads.

How does Da Vinci's bridge achieve stability without permanent connectors?

• By using nails and glue.

• Through the principle of friction.

• By interlocking metal pieces.

• With the help of ropes and pulleys.

Answer explanation

Da Vinci's bridge relies on the principle of friction to maintain stability. The design allows the pieces to press against each other, creating friction that holds them in place without the need for permanent connectors.

What was a significant military advantage of Da Vinci's bridge?

• It could be assembled and disassembled quickly.

• It was made of lightweight metal.

• It could support heavy artillery.

• It was camouflaged easily.

Answer explanation

Da Vinci's bridge could be assembled and disassembled quickly, allowing for rapid deployment in military operations, which was a crucial advantage in warfare.

What happens if one component of Da Vinci's bridge is removed?

• The bridge becomes stronger.

• The entire structure may collapse.

• The bridge becomes lighter.

• The bridge remains unaffected.

Answer explanation

Removing a component from Da Vinci's bridge compromises its structural integrity, potentially leading to collapse. Each part plays a crucial role in maintaining balance and support.

Why is Da Vinci's self-supporting bridge not commonly used today?

• It is too expensive to build.

• It requires modern materials.

• Its limited span poses challenges.

• It is not aesthetically pleasing.

Answer explanation

Da Vinci's self-supporting bridge has a limited span, making it impractical for many modern applications. This limitation poses challenges in terms of stability and load-bearing capacity, which is why it is not commonly used today.
