Question 1650 Deck General

The correct answer is C) 5.0. The mechanical advantage of a tackle system, neglecting friction, is equal to the number of rope parts supporting the load. In the illustration D029DG, the tackle number 5 has 5 rope parts supporting the load, which gives it a mechanical advantage of 5.0. The other options are incorrect because: A) 2.0 is too low, as the tackle has 5 rope parts. B) 4.0 is too low, as the tackle has 5 rope parts. D) 5.5 is too high, as the correct mechanical advantage is 5.0.
