Steel Drass B A light rigid bar is suspended horizontally from two vertical wires, one of steel and one of brass, as shown in the diagram. Each wire is 2.00 m long. The diameter of the steel wire is 0.60 mm and the length of the bar AB is 0.20 m. When a mass of 10.0 kg is suspended from the centre of AB the bar remains horizontal.
