(simple machine) pulley problems?

Please help by answering these 2 questions.

1.Using a block and tackle pulley System, determine the number of strands that will be needed to lift a weight of 5025 lbs. by applying 200 pounds of force?

2.Using a block and


1. If you do not count the strand between the applied force and the first pulley, the mechanical advantage is the number of strands.
So 5025/200 = 25.125, which means you would need 26 strands.

2. Again, I do not count the strand

The Da Vinci of robots

On a visit to the American Museum of Natural History in New York three years ago, Dennis Hong was captivated not by the giant blue whale, or the Tyrannosaurus rex skeleton, but by the ankle bone of a timid prehistoric deer.

The ‘double pulley’ ankle gave the creature more bounce in its stride, an evolutionary advantage that enables today’s suburban deer to bound gracefully over vegetable garden fences.
Hong took out his iPhone and snapped a picture of the diagram. He thought the concept might work nicely on his next robot. Another time, Hong watched a mother braid her daughter’s hair and wondered whether a robot could move in the same way. That led to the development of a three-legged walking machine that manoeuvres about with the same braiding motion.

A Chinese water-tube toy inspired Hong to create a species of robots that move by continuously turning themselves inside out. A cowboy’s lasso spurred him to build a robot that wraps around surfaces like rope.

(Ya Think!) He played video of Karl Rove saying that Perry "needs to fight the impression that he's a cowboy from Texas."

Sure, it has been one of the rare flops for Apple in recent years. And it could be so much more with say, a Blu-ray player or a web browser. But it is really good at its core functionality: bringing iTunes content into your living room. And thats why this new version of the Apple TV makes sense at least for now.
