Question 606 Deck General

The correct answer is B) Middle. The cargo boom is typically thicker at the middle section to provide the necessary strength and support to lift and move heavy cargo. The middle section of the boom has the greatest diameter compared to the narrower heel (base) and the tapered head (tip) of the boom. This design provides the optimal balance of strength and maneuverability for the cargo handling operations performed by the boom. The other options are incorrect because the heel and head of the boom do not have the greatest diameter, and the cargo boom does not have a uniform diameter along its entire length.
