A $0\mathrm{.}64$ kg yo$-$yo consists of two solid disks, each of radius $1\mathrm{.}8-m.$ joined by a massless rod of radius $0\mathrm{.}05*m.$ A string is wrapped around the rod. One end of the string is held fixed and is under tension as the yo$-$yo is released. The yo$-$yo rotates as it descends vertically. Find the tension in the string.

NOTE: ROUND OFF TO TWO DECIMAL PLACES IF NEEDED. SOME MAY ONLY NEED ONE DECIMAL PLACE.
