A steel wire is attached to two supports. The supports are attached to a ceiling. Initially, there is no tension in the wire when it is horizontal. A 96-N picture is then hung from the middle of the wire, as the drawing illustrates, so the ends of the wire make angles of 26 degrees with respect to the horizontal. What is the radius of the wire ? Assume that the wire has a circular cross section. (Young's modulus for steel is 2.0 * 10 ^ 11 * N / (m ^ 2) .)
