1.6-7/ A wire of length L 4 ft and diameter d-0.125 in. is stretched by tensile forces P = 600 lb. The wire is made of a copper alloy having a stress- strain relationship that may be described mathemat- ically by 18,000ɛ 0 < 8 < 0.03 (ơ = ksi) 1+ 300ɛ in which & is nondimensional and o has units of kips per square inch (ksi). (a) Construct a stress-strain diagram for the material. (b) Determine the elongation of the wire due to the forces P. (c) If the forces are removed, what is the permanent set of the bar? (d) If the forces are applied again, what is the proportional limit?
