Question 670 Deck General

The correct answer is A) increases as the boom's angle to the horizontal decreases. As the boom's angle to the horizontal decreases, the tension in the single span topping lift increases. This is because as the boom's angle becomes more horizontal, the vertical component of the load on the cargo hook increases, resulting in higher tension in the topping lift. Conversely, as the boom's angle increases, the vertical component of the load decreases, and the tension in the topping lift decreases. The other options are incorrect because B) is the opposite of the correct answer, C) implies a specific angle of 45 degrees, which is not necessarily true, and D) is also the opposite of the correct answer.
