the size of a shackle is determined by?

a the length of the pin

b the diameter of the body

c the diameter of the pin

d the length of the body

Explanation:

Identify shackle sizing standard

The nominal size of a rigging shackle is determined by the diameter of its bow (body) section, rather than the diameter of its pin.

Compare body and pin diameters

The pin diameter of a standard shackle is typically larger than the body diameter (usually by about \(1/8\) inch). Therefore, the rated size is defined by the diameter of the body.

Answer:

• (A) the length of the pin
• (B) the diameter of the body (Correct answer)
• (C) the diameter of the pin
• (D) the length of the body
