You are designing an industrial lighting fixture that will be suspended from the ceiling by several thin wires, each loaded in tension. The wires are to be made from a 260 Brass alloy having a yield strength (end of elastic deformation, beginning of permanent deformation) of 95 MPa and a diameter of 0.52 x 10-3 m and the total mass of the light fixture is 32 kg. Determine the minimum number of these brass wires that will be required to ensure there is no permanent deformation in the wires
