Is the mass of iron greater than, less than, or equal to the mass of aluminum? The mass of iron is greater than the mass of aluminum. This is an incorrectly stated question. Iron and aluminum are types of material, mass is the property of an object. The mass of iron is less than the mass of aluminum. The answer depends on temperature. The mass of iron is equal to the mass of aluminum.

Problem \#3 A nonuniform horizontal bar of mass 15 kg is supported by two massless wires against gravity. The left wire makes an angle $35^{\circ }$ with the horizontal, and the right wire makes an angle $55^{\circ }$ The bar has a length of 5.0 m The bar is in equilibrium. Find: (a) the tension of the left wire (in N) (1 point); (b) the tension of the right wire (in N) (1 point); (c) the position of the center of mass of the bar (in m), measured from the bar's right end (1 point).
