Wooden shoring, with a cross-sectional dimension of 4" X 4" should not be longer than __________.

Correct Answer: Option B — 10 feet

Standard damage control practices dictate that wooden shoring must be limited in length to prevent buckling under compressive loads. For a 4" x 4" timber, the maximum unsupported length is 10 feet. Exceeding this length significantly reduces the shore's load-bearing capacity, rendering it ineffective for supporting damaged bulkheads or decks.
