Question 2097Deck General70% to pass
You are using tackle number 5 as shown in illustration D029DG below to lift a weight. The hauling part of this tackle is bent to the weight hook (w) of tackle number 8. What is the mechanical advantage of this rig?
AI Explanation
The correct answer is B) 15.
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 5 has 5 parts of the hauling line supporting the load, which gives it a mechanical advantage of 5. Since the hauling part of tackle number 5 is connected to the weight hook (w) of tackle number 8, the total mechanical advantage of the rig is 15 (5 from tackle number 5 multiplied by 3 from tackle number 8).
The other answer choices are incorrect because they do not accurately reflect the number of parts of the hauling line supporting the load in this rig configuration.
