1.1 Sketch a typical stress-strain diagram for ductile materials. Clearly show the Elastic stage, Plastic range, Yielding points, Ultimate tensile strength and Failure point on the diagram. (9) 1.2 A cable consisting of a steel wire, 2.5 mm in diameter, surrounded by six bronze wire of the same size. If the allowable stress in the bronze is 60 MPa, find the safe load for the cable and the extension under this load on a length of 30 m (Est = 200 GPa and EBR = 80 GPa). (11) [20]
