I would ask what the deep meaning of the origin of the netwon is but yes a Newton is a kilogram meter / second squared. Because weight is a force (measured in Newtons) it is the mass time the gravity (gravity can also be seen as an acceleration downward caused by the earth)
That is the mass times the gravitational force (gravity). The product of these two magnitudes produces the weight. Note that mass is kilograms or slugs and weight is Newtons or pounds.
Assuming its too late to help maybe I can shine the light on some things. Of there is 3 ropes, each is supporting a third of the weight or close to it. Picture you have one rope and then divide it up into the three. mg=T1+T2+T3.
Total mg=mg+mgsin15+mgsin15.
The vertical rope would support more...
I never thought about the fact of having to actually produce the vapor but this does make a great deal of sense. Until later years, water would not be capable of said task which I'm sure I could have summed up better than how I did.
I also was curious after reading this post and i should do research before conversing about such a topic however, i do not think that water vapor would create the power to run the rotors the same that the fuel does. while water vapor can do many tasks that gas exhaust can, I'm not sure that it...
