Three masses are attached to a \(1.5\,\text{m}\) long massless bar. Mass 1 is \(2\,\text{kg}\) and is attached to the far left side of the bar. Mass 2 is \(4\,\text{kg}\) and is attached to the far right side of the bar. Mass 3 is \(4\,\text{kg}\) and is attached to the middle of the bar. At what distance from the far left side of the bar can a string be attached to hold the bar up horizontally?
