What does Jehovah Nissi mean?

In Exodus 17:15-16, the Name Jehovah-Nissi is used and means: The Lord Our Banner (or 'signal pole')Additional information:Jehovah-Nissi was the name of the alter that Moses put up after Israel defeated the Amalekites in Rephidim (Exodus 17:8,13-16). Depending on who translated the phrase, the meaning had a different slant. The Greek Septuagint translators felt that 'nissi' came from 'nus'(flee for refuge) so translated it: 'Jehovah is my Refuge'.The Latin Vulgate felt that 'nissi' came from Na-sas' (hoist, lift up) so translated it : Jehovah is my Exaltation. No matter how one translates 'nissi', the name of God, Jehovah (YHWH), is being glorified.

Did the Romans invent the treadwheel crane?

Yes. The Greeks invented cranes with the invention of the winch and pulley hoist. The Romans invented the treadwheel crane. The Romans adopted the cranes of the Greeks and massively improved on them. The simplest one was the trispastos, which had of a single-beam, a winch, a rope, and a block with three pulleys. It had had a mechanical advantage of 3:1, and single man operating the winch could raise 150 kg. The pentaspastos had five pulleys and the polyspastos had a set of three by five pulleys with two, three or four masts. The latter was worked by four men at both sides of the winch and could lift 3,000 kg. When the winch was replaced by a treadwheel, the load could be doubled to 6,000 kg with only half the crew, because the treadwheel had a larger diameter and thus a much bigger mechanical advantage.

How much work is done on a 100-kg crate that is hoisted 3 m in a time of 2 s?

-- The force required to lift the crate is equal to its weight.-- Weight of the crate = (M x g) = 100 x 9.8 = 980 newtons.-- Work = (force x distance) = 980 x 3 = 2,940 newton-meters = 2,940 joules.That's the work done to lift the crate, whether the worker takes a millisecond ora month to do the job. The amount of work the job requires doesn't depend onhow fast it's done.The rate at which the work is done is called power.-- If the work is done in 2 seconds, the power is 2,940/2 = 1,470 joules/second = 1,470 watts.-- If you're being paid by the hour, decide to stretch it out, and take exactly one hourto do it, then the power is 2,940/3,600 = 0.817 watt.-- If you're trying to make a good impression on the boss, and you complete the hoist in1 millisecond, then your power level is 2,940/0.001 = 2,940 kilowatts = 2.94 megawatts.-- If you could have completed the job a tiny bit faster ... in 1.97 rather than 2.0 seconds ...then the power would have been 2,940/1.97 = 1,492 watts = exactly 2 horsepower.But the amount of work is the same in every case.
