You are using tackle number 12 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 2. What is the mechanical advantage of this rig?
AI Explanation
The correct answer is C) 14.
The mechanical advantage of a tackle system is determined by the number of parts of the hauling line that are supporting the weight. In this case, the tackle number 12 has 7 parts of the hauling line supporting the weight, and the tackle number 2 has an additional 7 parts, resulting in a total mechanical advantage of 14.
The other options are incorrect because they do not accurately represent the number of parts of the hauling line supporting the weight in this specific tackle system configuration.
