I am not sure if this question belongs to this forum but i am going to ask it anyways.
Imagine that you have a 45 feet cylinder and inside you have 2 bars. from top to bottom the bars don;t go straight down instead the bars the bars get into the bottom by going around the whole cilinder (similar to a spiral shape).
My question is, how do i compute the length of any of those 2 bars?, for sure it should be longer than the whole cylinder but i have no idea.
In the attached file, there are the details. It says that every 16 ft it makes a complete revolution.
Please let me know if anyone knows about this.
