How anchors work.

Not exactly. Anchor alone is not holding the ship, but combination of the weight of chain or rope plus anchor. In the past when ships used ropes with anchors, the captain would release 7:1 ratio of the rope into the ocean. Now days ships use 4:1 ratio with chains. So in past if you would be in 150m of water you would need to release 1050m of rope. While with chain if you are in 150m of water you need to release 600 meters of chain. This ratio might also change depending if on the weather conditions or if you are in the water with strong currents.

In rare move, Congress pushes back on Trump over Library of Congress.

"Do you know how they take it back up?" Yes. They crank it straight up by moving the ship over the chain and anchor.

Its also the weight of the anchor so its not just the grip on the ocean floor

You're wrong for not doing a part two because of that question at the end do you know how they retrieve things

Doh! The ship doesn’t have move “forward due to inertia.” It moves forward due to momentum. Kids will fail science listening to this shit.

Wow, get out of the way of those chains

Yeah how to release that anchor would be good to know. Now u will be looking for that factoid all morning 🙄

Cables on ocean floor

Moves astern not ahead

….. duh.
