Question 4. Three wires are used to suspend the plate shown. Aluminium wires used at A and B with a diameter of 3 mm and a steel wire is used at with a diameter of 2 mm. Knowing that the allowable stress for aluminium (E = 72 GPa) is 96 MPa and that the allowable stress for steel (E = 200 GPa) is 124 MPa, determine the maximum load P th may be applied.
