How many of you are good enough at high powered math to solve this week's puzzzler?
It only took me about 10 minutes.
Here 'tis:
Jeff
About 10 seconds.

, I must be only half as smart as Jeff, 20 seconds.

Jim, I see we have a common middle initial. My middle name is Arnold. I never thought to ask why my folks picked that name but even though it would "fit" I'm just as happy that they didn't choose Edward or Ethan.
Jeff (Happy Passover to those celebrating it.)

In this case, there is no "higher math". The poles must be exactly touching for half of a 150' long rope to reach down 75'.

oops! I thought it was an old puzzler! (urk!)

I don't know the answer. I'm almost certain they misspelled "canary", though.

Mine did pick Edward, though I never suffered for it in school. The S is Edward's last name, so I had a good excuse, my grandfather's name sandwiched into my father's.

Less than five seconds.
Oh hell...
I was going to get out an ancient electrical engineering book that was full of wire droop formulas to figure it out...
I want my money back.

About 20 seconds.
I looked up "cantenary" (note spelling) and Wiki had the formula; I was all set to write a program that would try test values in the formula until I zeroed in on one that gave the answer. I wonder if in this case it would converge? I guess I now have one more useless thing to waste my ample "spare time" on. ;-)

"Catenary," of course.

It took me about a minute. I was thinking of looking up how hyperbolic trig functions work and the equations for determining aspects of a catenary then I got it.

You were not supposed to tell the answer!

"Catenary" (note spelling)

I already apologized! I thought it was an old puzzler. I worked this weekend! (sorry)

Reply: Actually 2x the thickness of the rope. Touching, the rope could not loop between them.
