A 1.80-m-long uniform bar that weighs 536 N is suspended
Chapter 15, Problem 63P(choose chapter or problem)
A 1.80-m-long uniform bar that weighs 536 N is suspended in a horizontal position by two vertical wires that are attached to the ceiling. One wire is aluminum and the other is copper. The aluminum wire is attached to the left-hand end of the bar, and the copper wire is attached 040 m to the left of the right-hand end. Each wire has length 0.600 m and a circular cross section with radius 0.280 mm. What is the fundamental frequency of transverse standing waves for each wire?

ANSWER:Solution 63P Step 1 of 4: The wire s have different linear mass densities so the frequencies are different. The bar is in equilibrium, so the forces and torques will balance. T + Tcop= 536 N = w alu
