🔍 Key Concepts

• Count how many sheaves (pulleys) are in the upper and lower blocks of tackle #8 • Note whether the hauling part P comes off the moving block or the fixed block • Review standard tackle names: single purchase, gun tackle, single luff tackle, parbuckle and how many sheaves each one uses

💭 Think About

• Look at tackle #8 and compare it carefully with tackles #1, #2, and #3: which ones have the same arrangement of sheaves and lead of the fall? • Ask yourself: does tackle #8 have one sheave in each block, or is one of the blocks double-sheaved? How does that match the textbook definitions of each choice? • Is tackle #8 used to roll or turn the load (like on a drum) or simply to lift it straight up? Which option name matches that function?

✅ Before You Answer

• Verify the number of sheaves in the upper (fixed) block and the lower (moving) block • Check where the standing part is made fast and where the hauling part leads out • Confirm which option name corresponds to that exact combination of sheaves and lead of the fall, not just the mechanical advantage
