Authoritative PPT Summary
"Building a "Bridge" with Paper" Shape and Structure PPT Courseware 4
A piece of newspaper is thin and soft. Can it be used to build a "bridge"? Within the specified time, use a piece of newspaper and a small amount of tape to build a "bridge" that can span a 35 cm wide "canyon", be wider than 10 cm, and be able to carry a "vehicle" weighing 200 grams.
Prepare: an old newspaper, tape, scissors, ruler.
Discussion summary
First, consider the characteristics of paper. The characteristic of paper's endurance is that it is resistant to tension but not compression, that is, its ability to resist bending is very poor. Paper is a "thin plate" material, so we need to consider how to enhance its bending resistance.
Second, what shape and structure should we choose for our bridge. These two aspects are interconnected and influence each other, and must be considered and selected together.
In addition, paper is limited, what parts does our bridge consist of, how much material is used for each, and how to connect them firmly together...
Paper Bridge Reference Picture
Siamese double tube bridge
Roll the newspaper into two cylinders and connect them with tape. Adding tape horizontally to the mouth of the barrel can strengthen the support.
Straight tube frame bridge. The paper tube is connected with tape to form a "mesh"-shaped frame, and then glued to the "bridge deck".
Triangular suspension bridge. Use tape to make "steel cables" and the bridge deck into a trough shape.
Reinforcement of trough bridge. Similar to the straight tube frame, the bridge deck is grooved to increase its resistance to bending.
How to introduce our "bridge"?
The length and width of the paper bridge and its load-bearing capacity.
How we change the shape and structure of paper and what science we apply.
How our design ideas are formed.
What difficulties were encountered during the production process and how were they solved?
What areas are not good enough and how can they be improved.
fill in the blank:
1. According to the different structures of bridges, bridges can be divided into many types. There are four basic types: _____, _____, _____, and floating bridge.
2. The steel cable bridge is composed of _____, _____ and bridge deck; its salient features are: _____ From a functional point of view, __________.
3. For an arch bridge whose deck is under the arch, the bridge deck can pull _____ and offset the outward _____ of the arch. The bridge deck is tensed by the force in the _____ direction, which also increases the bridge deck's resistance to bending.
4. Huge stone arches in nature have stood firm for thousands of years. People were inspired by nature to build _____, _____ and arch bridges.
5. In the activity of building a cable bridge, when we pull the rope straighter, we feel the force _____ (larger/smaller).
6. According to the materials used to build the bridge, there are _____ bridge, _____ bridge, etc.; according to the structure of the bridge, there are _____ bridge, _____ bridge, _____, _____, etc.
7. We can use __________, __________, __________ and other methods to enhance the object's ability to resist bending.
judge
1. The most important thing when designing and making a bridge is to consider that the bridge can bear load and will not bend. ----------( )
2. Changing the shape of an object can change its ability to resist bending. ---------------( )
3. The bending resistance of two pieces of paper must be stronger than that of one piece of paper. --------------------------( )
4. Most of the ancient city gates were built in an arched shape just for the sake of appearance. ----------------( )
