Authoritative PPT Summary
"Shape and Bending Resistance" Shape and Structure PPT Courseware 3
do you remember?
What is the bending resistance related to:
1. Thickness of material
2. Width of material
3. Types of materials
Can you guess?
Assuming that the thickness, width, and type of the material remain unchanged, will the bearing capacity of the material remain unchanged?
What problem did you find?
Teacher demonstration experiment
Students who observed carefully, what problems did you find?
This experiment tells us: the bearing capacity of a material is not only related to the thickness, width, and type of the material, but also to the shape of the material
It’s time to use your ingenuity!
Are these materials more resistant to bending when they are made into different shapes than when they are not made into such shapes? How do you know?
Think about experiment plan
Why are you hesitating? Let’s get started!
That’s what happened!
Why are materials with these shapes more resistant to bending than flat sheets?
In fact, the width is reduced and the thickness is increased, because thickness can enhance the bending resistance of the material more than width, so the bearing capacity is increased!
