Question 2096Deck 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 of tackle number 9. What is the mechanical advantage of this rig?
AI Explanation
The correct answer is A) 20.
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 5 has 10 parts of the hauling line supporting the weight, and the tackle number 9 has 2 parts of the hauling line supporting the weight. Therefore, the mechanical advantage of this rig is 10 x 2 = 20.
The other options are incorrect because:
B) 9 is the number of parts of the hauling line in tackle number 9, not the mechanical advantage.
C) 5 is the number of the tackle, not the mechanical advantage.
D) 4 is incorrect as the mechanical advantage is 20.
