I'm slightly confused - nothing new there!DaveC426913 said:You misunderstand my post. (And you are, at least technically, incorrect, though you are correct in spirit).
The poster is correct in principle that it forms a parabola (which, technically, it does). It's just a parabola with some very unique values (Google "degenerate parabola") and I expect that if he did the calculations the hard way, he would still arrive at the correct answer - and then slap himself on the forehead.
I'm trying to hint to him that *knowing* it is a parabola is not going to get him to the *easy* answer.
I think I am the "poster" you're referring to, I did get the answer almost straight away -at least as soon as I tried to draw the situation.
But the link you posted says:
"In 1669, Jungius disproved Galileo's claim that the curve of a chain hanging under gravity would be a parabola"
Now you say it is a parabola, or at least a special kind of parabola.
So who's right? You, me, Galileo or Jungius (whoever he might be)
Lastly don't you think it's about time somebody "put some ink in their pen" and writes the answer in a readable form?
