"The Power of Arch" Shape and Structure PPT Courseware

1. What is the bending resistance of the beam related to?

(The bending resistance of the beam is related to the width and thickness of the beam)

2. After doing two experiments, we found:

As the width of the paper increases, its resistance to bending (also increases),

The thickness of the paper increases and its ability to resist bending (greatly increases).

3. Bending thin materials into various shapes actually reduces the width of the material and increases the thickness of the material. Although reducing the width of the material reduces some resistance, increasing the thickness greatly enhances the material's resistance to bending.

Explain why the watermelon skin arch is not carried on the shoulder?

Answer: Because the watermelon skin arch transmits the force downward and outward to the adjacent parts, the various parts of the arch squeeze each other and are more closely combined. Therefore, the watermelon peel arch cannot be carried on the shoulder.

Exercise book page 19 Extracurricular development?

Answer: Because the arch is compressed and will produce an outward thrust. As long as it resists this force, it can withstand a lot of force. Therefore, the arched structure can withstand pressure better than the beam.
