Question: A solid 0 . 1 2 in . diameter steel E = 3 0 , 0 0 0 ksi; a = 6 . 5 1

A solid 0.12 in. diameter steel E=30,000ksi;a=6.510-6F wire is stretched between fixed supports so
that it is under an initial tension force of 35lb. If the temperature of the wire drops 81F, what is the tensile
stress in the wire?
draw the fbd aswell
Ans in psi
A solid 0 . 1 2 in . diameter steel E = 3 0 , 0 0
