"The Power of Arch" Shape and Structure PPT Courseware 4

How do paper arches deform?

Roll the paper first and then loosen it to make an arch. Use an iron washer to test how much pressure it can withstand. Experiment many times.

Use more books to press against the arch feet on both sides to maintain the arch shape, and use iron washers to test how much pressure it can withstand. Experiment many times.

what have you found?

By supporting the arch's feet, the arch can withstand greater force.

Can you explain why?

When the arch is pressed, it will squeeze downwards and outwards, and the pressure against the arch's feet will offset its force of squeezing to both sides.

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.

Reasons why the watermelon rind cannot be carried on the shoulder:

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