What are the key differences between concentric and radial fractures?

• Concentric fractures are circular, while radial fractures radiate from a central point.

• Concentric fractures radiate from a central point, while radial fractures are circular.

• Concentric fractures are linear, while radial fractures are circular.

• Concentric fractures are random, while radial fractures are patterned.

How can you determine the order of impact from the fracture patterns?

• By analyzing the sequence of fracture lines

• By measuring the depth of each fracture

• By counting the number of fractures

• By examining the color of the fracture surfaces

What will you have after completing the Glass Analysis Lab?

• A certificate of completion

• A detailed report on glass properties

• An understanding of glass analysis techniques

• A set of glass samples

Station 1: Explain the difference between radial and concentric fractures.

• Radial fractures spread out from the point of impact, while concentric fractures form circular patterns around the point of impact.

• Radial fractures form circular patterns around the point of impact, while concentric fractures spread out from the point of impact.

• Radial fractures and concentric fractures are the same and have no difference.

• Radial fractures occur only in metals, while concentric fractures occur only in glass.

Station 2: How do you determine the sequence of impacts on glass?

• By analyzing the fracture patterns

• By measuring the thickness of the glass

• By checking the color of the glass

• By weighing the glass pieces

What are radial fractures?

• Fractures that radiate outward from the point of impact

• Fractures that occur in a circular pattern

• Fractures that are parallel to each other

• Fractures that occur only in bones

Which type of fracture encircles the whole?

• Radial Fractures

• Concentric Fractures

Looking at the sample, determine whether the arrow labeled '1' is pointing to a radial or concentric fracture.

• Radial

• Concentric

Looking at the sample, determine whether the arrow labeled '2' is pointing to a radial or concentric fracture.

• Radial

• Concentric
