Binding indicates that the links have which condition because the sides bow inward and prevent adjacent links from moving freely?

• A. compressed
• B. cracked
• C. stretched
• D. twisted

Answer: (C)

Binding shows the chain is in a stretched condition. When a chain is stretched, wear at the pins and plates causes the sides of the links to bow inward, reducing the clearance between adjacent links. That inward bowing makes the links press against each other and bind, so they can’t move freely. Other defects would present differently—for example, cracks, twists, or improper alignment don’t produce the same inward bowing and binding pattern. So the condition indicated by binding is stretched.
