203. 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?
The mechanical advantage is 14. Tackle 12 provides a 7:1 advantage, and tackle 2 provides a 2:1 advantage. As a compound tackle, their advantages multiply: 7 x 2 = 14.
