A uniform 165N bar is supported horizontally by two identical wires A and B (Figure 1). A small 185 N cube of lead is placed three-fourths of the way from A to B. The wires are each 75.0 cm long and have a mass of 5.50 g. A B Cube Bar The bar hangs on two vertical wires A and B, attached to the ends of the bar. The cube is placed on the bar three fourth of the way from A to B. Part A If both of them are simultaneously plucked at the center, what is the frequency of the beats that they will produce when vibrating in their fundamental? Express your answer with the appropriate units. A uniform 165N bar is supported horizontally by two identical wires A and B (Figure 1).
