Question 1652 Deck General

The correct answer is D) 24. The mechanical advantage of a tackle system is determined by the number of rope parts supporting the load. In this case, the tackle number 4 has 4 rope parts, and the hauling part of this tackle is bent to the weight hook of tackle number 11, which also has 4 rope parts. Therefore, the overall mechanical advantage of this rig is the product of the individual mechanical advantages, which is 4 x 4 = 16. The other options are incorrect because they do not correctly account for the combined mechanical advantage of the two tackle systems. Option A) 4 is the mechanical advantage of just the first tackle, while options B) 6 and C) 10 do not accurately represent the combined mechanical advantage of the two tackle systems.
