A vertically suspended wire has a cross-sectional area of 0.1 in.². A downward force, applied to the end of the wire, causes the wire to stretch. The force is increased linearly from initially zero to 2500 lb, and the length of the wire increases by 0.1%. Select a wire length and use it to determine

(a) the normal stress, in lb/in.², and

(b) the work done in stretching the wire, in ft #lb.
