Log diameter refers to?

Log diameter refers to?

• A. The length of a log.
• B. The moisture content of a log.
• C. The width across its circular end, critical for calculating volume.
• D. The number of rings in a log.

Answer: (C)

Log diameter is the width across the log’s circular end. This measurement matters because volume is found by cross‑sectional area times length, and the cross‑section is roughly circular. The area of a circle depends on its diameter: A = π*(D/2)², so knowing the diameter directly determines the cross‑sectional area used in volume calculations. In practice, diameter is often measured at the large end to standardize estimates, though a log can taper along its length, causing diameter to vary. The other factors like the log’s length, moisture content, or the number of rings relate to different properties or calculations and do not define the log’s diameter.
