Cargoes with a density of 1,780 kg/m3 and above (heavy cargoes) include iron ore, pig iron, steel, bauxite and cement. Lighter cargoes, but with a density of more than 1,000 kg/m3, include grains such as wheat and rice, and timber.

così vengono calcolate le resistenze al carico per le navi cargo.

Did Russian early-warning system see the meteorite?

The meteorite that exploded over Chelyabinsk on February 15, 2013, was a pretty big thing .... Surely it should have been detected by someone.

Skyfall: will a Russian meteor and an asteroid flyby change our minds about the NEO threat?

.... how did the object escape detection by the various surveys for NEOs?

Part of the reason is its small size, but its orbit played a key factor as well.

“The reason why it wasn’t detected by telescopes on Earth is because it literally came out of the day side of our planet. It was in the daylight sky” and thus couldn’t be seen ....

Volume sfera è 4/3 x 3.14 x R3 giusto?

 

Il raggio di una sfera di 17 metri di diametro sarebbe 8,5 m, cioè 85 dm.

 

Volume di tale sfera = 2.570.493,8 dm3.

 

Peso specifico ferro = 7,8 Kg/dm3

 

Peso della sfera a me viene = 20.049.852,28 Kg = 20.049,852 tonnellate.
