(...) Whew, good thing the NSF funded that. Otherwise, we might be stuck with a shrinking universe, and who wants that? (...) See, now, if you ask me, I'd say they could have skipped that one. (22 years ago, 9-Jan-03, to lugnet.off-topic.geek)

(...) I'll say "sure" but with this question as a follow-up. Pulleys are usually used on Earth to gain a mechanical advantage.

Imagine a winch pulling a rope or cable through a series of pulleys (horizontal) that are staked to the ground. The pulleys are arranged so that the rope makes a zig zag pattern on the ground. There is an object at one end of the cable, being reeled (...) (22 years ago, 28-Dec-02, to lugnet.off-topic.geek, lugnet.space)
