Understanding Structural Forces and Functions

What is the main purpose of a structure?

• To be made of strong materials.

• To hold things up or pull things.

• To be found only in buildings and bridges.

• To be flexible and stretchy.

What does the phrase "Form follows function" mean for structures?

• The appearance of a structure is more important than its use.

• The shape of a structure is determined by what it is made of.

• The shape of a structure is designed based on what it needs to do.

• Structures are always built in the most beautiful way possible.

When a material is being pulled, what is the force called?

• Compression

• Tension

• Pressure

• Flexion

Why are eggs considered strong structures?

• They are made of very hard material.

• Their oval shape helps spread out weight evenly.

• They are small and lightweight.

• They are designed to break easily from the inside.

What is the primary difference between a structure under compression and one under tension?

• Compression structures are pulled apart, while tension structures are pushed together.

• Compression structures are pushed together, while tension structures are pulled apart.

• Compression structures are always thin, while tension structures are always thick.

• Compression structures are found in nature, while tension structures are man-made.

In a flagpole, which part is primarily under tension?

• The base of the pole.

• The top of the pole.

• The rope used to raise the flag.

• The flag itself.

Why can three eggs support a heavy book and soup cans when arranged in a triangle?

• The eggs are naturally very strong and unbreakable.

• The weight is concentrated on a single egg, making it stronger.

• The triangular arrangement helps distribute the weight evenly across all three eggs.

• The book and soup cans are lighter than they appear.

Which of the following is considered a structure?

• A tree

• A barbecue grill

• A hot dog

• All of the above

What two main forces can act on a structure?

• Push and pull

• Tension and compression

• Gravity and friction

• Stress and strain

Why is it important for tall buildings to be flexible?

• To make them look more modern.

• To allow them to sway without breaking during wind or earthquakes.

• To make them easier to build.

• To reduce the amount of material needed.
