consider a cylindrical nickle wire 1.9 mm in diameter and 3.0*104 mm long. calculate its elongation when a load of 260 N is applied. Asuume that the deformation is totally elastic and that the eleastic modulus for nickel is 207 GPa (or 207* 109 N/m2)

A wine 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 mathematically by =18,0001+30000.03(=ksi) in which is nondimensional and has units of kips per square inch (ksi). (a) Construct a stress-strain diagram for the material. (bj 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?

The rails of a railroad track are welded together at their ends (to form continuous rails and thus eliminate the clacking sound of the wheels) when the temperature is 60°F. What compressive stress ?? =6.5×10-6 /? is produced in the rails when they are heated by the sun to 120"F if the coefficient of thermal expansion a = the modulus of elasticity E = 30 × 106 psi?

A steel (E=30x106 psi) rod 10m long and 5cm in diameter is subjected to a compressive force of F=1000 N. Find the deformation of the rod.
