Strengthening Materials

Strengthening Materials

1. Why do we need to strengthen materials? Structures like buildings must be strong enough to stand firm against powerful winds, hail and rainstorms. Sometimes they also have to support heavy loads. Strong materials are used to build strong structures.

2. Folding: Some materials can be strengthened by changing their shape. The shape of materials can be changed by folding. Example, we use boxes to pack things in the 2 layer is folded.

3. Hollow Pillars: We can strengthen materials by folding or shaping them into circular, triangular or square pillars.

4. Struts: Structures are strengthened by using struts. They are from a strong material. They can be made stronger, by rolling them into long, thin tubes.
