🔍 Key Concepts

• Count how many blocks and how many sheaves (grooves) are in each block for tackle #2. • Recall that a whip uses only one single block, while other tackles use two blocks. • Think about how many parts of the fall (sections of rope supporting the load) are at the moving block in tackle #2.

💭 Think About

• Compare tackle #2 with tackle #1 and #3. How does the arrangement of blocks and the reeving of the line change from one to the next? • For tackle #2, where is the standing part of the line made fast, and how many rope parts are actually lifting the weight? • Which of the answer choices describes a system with two single-sheave blocks and a mechanical advantage equal to the number of rope parts at the moving block?

✅ Before You Answer

• Verify exactly how many blocks are in tackle #2 and whether they are fixed or moving. • Verify how many rope segments are directly supporting the weight in tackle #2 (this equals the mechanical advantage, ignoring friction). • Match that configuration to the standard textbook names of tackles: whip, gun tackle, onefold/single purchase.
