Determine the magnitude of tensile force and corresponding normal stress of a wire

A 28-ft length of 0.25-in.-diameter steel wire is to be used in a hanger. It is noted that the wire stretches 0.55 in. when a tensile force P is applied Knowing that E = 29 X 10 (to the 6th power) psi, determine (a) the magnitude of the force P, (b) the corresponding normal stress in the wire.

a) 1.19 kips; 51.68 ksi

b) 2.33 kips; 47.42 ksi

c) 7.25 kips; 23.61 ksi

d) 4.23 kips; 37.83 ksi
