Description

"Resisting Bending" Shape and Structure PPT Courseware 5

Look at the house and bridge below. Are they similar in shape and structure?

Let's be little architects together and study the bending resistance of beams to make our houses and bridges stronger.

What factors are related to the bending resistance of beams?

Our speculation

The bending resistance of a beam is related to its material

The bending resistance of a beam is related to its length

The bending resistance of a beam is related to its width

The bending resistance of a beam is related to its thickness

Study 1 Width and bending resistance of paper beams

Discussion: What conditions should be kept constant in the experiment? What conditions need to be changed?

Kind tips

First predict, then experiment, then record, and finally summarize the findings based on experimental data.

During the experiment, the paper clip should be placed gently in the middle of the paper bridge to avoid collapsing the paper bridge.

A paper bridge collapses when it hits the bottom, but the last paper clip that caused the collapse does not count.

Ask each group to experiment quietly. After completing the group, please sit upright and compare which group is faster and quieter.

Study 2 Thickness and bending resistance of paper beams

Discussion: What conditions should be kept constant in the experiment? What conditions need to be changed?

Prediction: Write down the predicted results

Actual measurement: Keep records and the team leader will report the data in a timely manner.

Analysis: Study the data and write down your findings

in conclusion

The relationship between the width of the paper beam and the bending resistance is: the wider the paper beam, the stronger the bending resistance.

The relationship between the thickness of the paper beam and its bending resistance is: the thicker the paper beam, the stronger its bending resistance.

judge

1. The thickness of paper is directly proportional to its bending resistance. ( )

2. Beams placed horizontally can withstand greater pressure than placed vertically. ( )

3. Beams are easier to bend and break than columns. ( )

4. The bending resistance of two pieces of paper must be stronger than that of one piece of paper. ( )
