C) 15 in‑lb D) 20 in‑lb Answer: B Explanation: The torque should follow the manufacturer’s recommendation; over‑tightening can strip the wood. Question 19. A mounting bracket is installed on a concrete wall using a sleeve anchor rated for 250 lb. If the actual load is 180 lb, does the installation meet a 5× safety factor? A) Yes, because 250 lb ÷ 180 lb = 1. B) No, because 250 lb ÷ 180 lb = 1.39, which is less than 5 C) Yes, because the anchor rating exceeds the load D) No, because concrete cannot hold any load Answer: B Explanation: The safety factor is 250 ÷ 180 ≈ 1.39, which is well below the required 5× factor.
