Brittle and Ductile Fractures Quiz

What is a key characteristic of brittle failure?

• It only occurs in metals.

• It involves significant stretching before breaking.

• It happens suddenly without warning.

• It occurs gradually over time.

Which of the following is an example of plastic deformation?

• A metal rod bending under pressure.

• A rubber band snapping instantly.

• A glass shattering when dropped.

• A ceramic plate cracking.

What happens to a material undergoing plastic deformation?

• It breaks without any prior warning.

• It stretches and then breaks.

• It remains unchanged.

• It melts.

How does brittle failure differ from plastic deformation?

• Brittle failure involves stretching before breaking.

• Plastic deformation happens instantly.

• Plastic deformation only occurs in glass materials.

• Brittle failure occurs without warning, while plastic deformation involves stretching over time.

What is the main focus of the final part of the discussion?

• The causes of brittle failure.

• The process of plastic deformation.

• The differences between brittle failure and plastic deformation.

• The applications of different materials.
