"Resisting Bending" Shape and Structure PPT Teaching Courseware

Part 1: Importing new lessons

We know that houses and bridges are supported by columns and beams. It can be seen that the beam bears a lot of pressure, so what is the bending resistance of the beam? Let’s study it today.

Resistance to bending PPT, part 2: new lesson learning

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

Many houses and bridges are supported by upright materials (pillars) and horizontal materials (beams). When they are under pressure, beams are easier to bend and break than columns. Therefore, how to enhance the bending resistance of beams is a very important issue in architecture.

What factors are speculated to be related to the bending resistance of the beam?

Why do we speculate this?

The width and resistance of paper to bending. We pad both ends of the paper beam to a certain height, so that the paper beam is under pressure, and the middle part touches the table as a standard for bending. The number of load-bearing washers indicates the bending resistance of the paper. (thin cardboard paper)

Resistance to bending PPT, part three: conclusion summary

As the thickness of the paper increases, the bending resistance will be greatly increased. The beams are placed vertically, that is, the thickness of the beam is greater than the width.

Resistance to Bending PPT, Part 4: Classroom Exercises

(1) True or False Questions (mark √ if correct, × if incorrect)

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

2. Beams placed flat 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. ( )

(2) Multiple choice questions

1. When studying the relationship between paper width and bending resistance, the following conditions remain unchanged ( ).

A. The length and thickness of the paper B. The length, width and thickness of the paper C. The width of the paper

2. The thickness and width of the material, the material () affects the ability to resist bending.

A. Same degree B. More thickness C. More width

Resistance to bending PPT, part 5: homework arrangement

Why are the beams placed upright? How do you use a ruler (or sorbet chip) to prove your point?
