Question 278 Deck General
70% to passStress on the topping lift of a swinging boom can be reduced by _______________.
A
Raising the boom
B
Rigging a back stay
C
Taking all slack out of the preventer
D
Increasing the mechanical advantage of the cargo purchase
AI Explanation
The correct answer is A) Raising the boom. Raising the boom reduces the stress on the topping lift by decreasing the angle between the boom and the topping lift. This lower angle results in less tension on the topping lift, which helps prevent excessive strain or damage. The other options, such as rigging a backstay, taking slack out of a preventer, or increasing the mechanical advantage, do not directly address the stress on the topping lift caused by the boom's angle.
