A nonuniform, horizontal bar of mass 3.43 kg is supported by two massless wires against gravity. The left wire makes an angle 21.9 degrees, with the horizontal, and the right wire makes an angle 61.8 degrees. The bar has length 1.04 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 (T_2)?

C) What is the tension in the wire in the left side of the bar (T_1)?
