"Making a Frame" Shape and Structure PPT Download

Part One: Scientific Practice

Advantages of the frame structure: The frame structure can support objects, function as columns and beams, and consumes less material.

Make a simple framework

Experiment name: Build a triangular frame and a quadrilateral frame

Experimental materials Bamboo chopsticks, rubber bands, bamboo skewers or plastic straws

Experimental steps

1. Use rubber bands and bamboo chopsticks to tie the frame;

2. Observe the difference between them when they are acted upon by force, and see which one is easily deformed?

Make a solid cube frame

experimental method:

1. Make the upper and lower sides first, and then use 4 chopsticks to connect the upper and lower sides.

2. The rubber band is wrapped in the same way as in the rectangular frame.

3. Each side should be as identical as possible.

4. Students in groups divide work and cooperate.

Consider analyzing:

How to strengthen this cube frame with fewer diagonal bars? Take an inclined rod as an example and analyze its function.

Taking into account material saving, inclined rods can be added to the six sides, or inclined rods can be added to the interior. Diagonal bars can prevent the frame from tilting and collapsing.

Making framework PPT, the second part: expansion and extension

Frame structure refers to a structure in which beams and columns are rigidly or hingedly connected to form a load-bearing system.

The triangular frame in the frame structure has stability, and the triangular frame can be used to strengthen the frame structure. The quadrilateral frame is unstable and can be strengthened by adding a diagonal rod to the quadrilateral frame.

Make framework PPT, the third part: practice in class
