Strong material

The video tutorial explains that strong materials resist wear and physical force. It highlights that materials can exhibit strength in different ways, such as ceramics and concrete being strong under compression, while nylon and carbon fibers are strong under tension.

What characteristic defines a strong material?

• Ability to conduct electricity

• Resistance to wear and physical force

• Transparency to light

• Flexibility under pressure

In what ways can materials demonstrate strength?

• By being lightweight

• By being colorful

• By being expensive

• By being strong in different ways

Which materials are known for their strength in compression?

• Nylon and carbon fibers

• Ceramics and concrete

• Glass and rubber

• Wood and plastic

What type of force do nylon and carbon fibers resist effectively?

• Shear

• Compression

• Torsion

• Tension

Which of the following is an example of a material strong under tension?

• Wood

• Nylon

• Ceramics

• Concrete
