Question 2098 Deck General

The correct answer is C) 18. The mechanical advantage of a tackle system is determined by the number of parts of the hauling line that are supporting the load. In this case, the tackle number 6 has 6 parts of the hauling line supporting the load, which gives it a mechanical advantage of 6. Since the hauling part of tackle number 6 is connected to the weight hook (w) of tackle number 8, the overall mechanical advantage of the rig is the product of the mechanical advantages of the two tackles, which is 6 x 3 = 18. The other answer choices are incorrect because they do not correctly account for the combination of the two tackle systems. Option A (11) and B (16) are too low, while option D (24) is too high.
