More rope mechanical advantage: the 7:1

Thank you for posting, I’m starting to understand how this all works. I have no real application for all of this but it’s interesting to watch they see the mechanical advantage.

Good. If you watch my whole series on MA it should make things much clearer as you will develop building block recognition and patterns. Thanks for watching!

I don't see 7:1. How are you adding the Tensions?

On which example? What are you coming up with out of curiosity? I should probably do a followup video showing how it all adds up.

Something I've never understood, maybe you can answer. Let's say you're lifting a 1800lbs, using the 7:1 shown here. Do the blocks have to be rated for 1800lbs or less, since the advantage?

The 1800lbs never weigh less than 1800lbs. The mechanical advantage only facilitates using less than 1800lbs to lift the weight. So yes, your equipment has to be rated for whatever you are lifting, even if your effort is less. Cheers
