Description

"Shape and Bending Resistance" Shape and Structure PPT Courseware 4

What is the relationship between the bending resistance of a beam and its width and thickness?

The wider the beam, the greater its resistance to bending.

The thicker the beam, the more resistant it is to bending.

think:

1. Why are some steel or aluminum materials made into shapes such as "T", "U", "L", "work" or "口"?

2. Are these shapes related to bending resistance?

When experimenting, we should pay attention to:

1. Only the shape of the paper can be changed, the distance and height of the piers cannot be changed, and the thickness, length and size of the paper cannot be changed.

2. Each piece of paper can only be used once and cannot be used repeatedly or together.

3. Heavy objects should be placed as far as possible in the middle of the paper bridge and placed gently.

4. The heavy object that makes the paper hit the table cannot be recorded.

Experiment: How many layers of corrugated cardboard are there? What is the thickness, hardness, and shape of each layer? What is the bending resistance?

The same thin material: changing the shape can enhance the material's ability to resist bending.

Increasing the thickness can greatly enhance the material's ability to resist bending.

Stacking materials of the same thin type and different shapes together greatly increases its load-bearing capacity
