Part One: Exploration Experiment

What is the relationship between the bending resistance of beams (1)

Precautions:

1. Use cardboard about 0.5 mm thick, and cut the paper into strips of about 25 cm long, 3 cm, 6 cm, and 12 cm wide.

2. In order for the paper strip to be used multiple times without being excessively bent, in the experiment, the height of the paper strip should be controlled at about 2 cm.

3. Keep experimental records.

What does the bending resistance of a beam have to do with (2)

Precautions:

Cut the 0.5 mm thick paper into strips about 25 cm long and 3 cm wide, then divide them into two and four pieces and stick them together and flatten them to make 1 sheet, 2 sheets, and 4 sheets of paper. And there are three paper beams of equal length and width. Keep good experimental records.

Conclusion: As the thickness of paper increases, the bending resistance will be greatly enhanced.

Resist bending PPT, part 2: expansion and extension

The bending resistance of a beam is proportional to the width of the beam, proportional to the square of the height of the beam, and inversely proportional to the length of the beam.

The Chinese proverb "the house does not collapse when the wall falls" fully expresses the characteristics of the beam-and-column structural system.
