Homework Equations

The Attempt at a Solution

I really haven't the slightest clue how to read this diagram. I see nothing resembling a U.

 

[lewando]

It is a U with 90° bends instead of the usual smooth bend.

 

[1MileCrash]

Still not sure I follow.. if the wire spans from point D to point E, how could it be bent at those 90* angles where shown?

 

[lewando]

The wire is bent at D and bent at E. I am confused about your confusion.

Okay, my confusion was that the thicker part of the line represented the wire, and that the thinner lines were some kind of axis... really the garbagetiest diagram I've ever seen of anything.

Thanks for your help.

De nada.
