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) .)

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
