Description

"The Power of Arch" Shape and Structure PPT

Part 1: Testing the load-bearing capacity of the paper arch

Make a paper arch and see how much weight it can bear.

How do paper arches deform?

When the arch is under pressure, the arch legs will push to both sides, producing an outward pushing force.

How can I keep the shape of the paper arch unchanged?

Use two books to secure the arch's feet and test how much weight the paper arch can bear.

Observe how the shape of the paper arch changes as the bearing capacity increases.

How can the paper arch be made to carry more weight?

Use more books to secure the arch's feet and test how much weight the paper arch can bear.

The secret of arch load-bearing

When the arch carries weight, it can transmit the pressure downward and outward to the adjacent parts. The various parts of the arch squeeze each other and combine more closely.

Pressure on the arch will produce an outward pushing force. Against this force, the arch can carry a large amount of weight.

The power of the arch PPT, part two: building a melon-skin arch

Taking advantage of the characteristics of the arch, people can build very large arches using small pieces of bricks and stones.

Let's give it a try.

Cut the semicircular watermelon rind into 5 pieces, paying attention to the direction of the cuts, and then carefully build a watermelon rind arch.

Can we explain why the watermelon skin arch doesn't collapse?

The watermelon rind arch transmits the force it receives downward and outward to the adjacent parts. Each part of the arch is squeezed against each other and combined more closely, so the watermelon rind arch will not collapse.
