Block And Tackle A Block And Tackle Is Used To Lift A 200kg Crate Of Dead Crabs Out Of A Cruise Ship. It Consists Of 6 Pulleys?
A block and tackle is used to lift a 200kg crate of dead crabs out of a cruise ship. it consists of 6 pulleys? - block and tackle
and 6 cables, the weight and 1 rope used to exert a downward force. when 10 crabfishermen with a force of 40.4N each field still draw on the deck of the cruise ship.
>> What is the proper role of mechanical advantage?

6 blocks, the top 3, does not alter the mechanical effect, but only the direction of the rope down. Pulleys at 3 each double the mechanical effect of the rope through it. Thus, the first lower roller reduces the weight of 200 kg to 100 kg shoot. The second reduces the removal of 100 kg to 50th The lower roller takes the third pull 50 kg to 25 kg traction. This does not include losses due to friction in the pulleys.
