A nonuniform, horizontal bar of mass 3.85 kg is supported by two
massless wires against gravity. The left wire makes an angle
31.9 degrees, with the horizontal, and the right wire makes an
angle 52.1 degrees. The bar has length 1.77 m. A) Find the
position of the center of mass of the bar, x, measured from the
bar's left end. B) What is the tension in the wire in the right
side of the bar C) What is the tension in the wire in the left
side of the bar
