A machine has an 650 g steel shuttle that is pulled along a square steel rail by an elastic cord (see figure below). The shuttle is released when the elastic cord has 16 N tension at a 45° angle
A steel wire strung between two supports is initially horizontal when there is no tension on it. When a 9.5 kg painting is hung on the wire, the wire makes a 25° angle to the horizontal, as shown. Illustrate what is the diameter of the wire?
