A continuous cable (diameter 6 mm) with tension force T is attached to a horizontal frame member at B and C to support a sign structure. The cable passes over a small frictionless pulley at D. The cable is made of a copper alloy, and the stress-strain relationship for the cable is 124,000 ()= 0 0.03 (o in MPa) 1 +300 a. Construct the stress-strain diagram and estimate the elastic modulus E of the material. b. Estimate the yield stress oy of the material using the 0.2% offset method. c. The normal strain & in the cable due to the applied load.
