A cylindricаl rоd 0.5 m lоng аnd 0.01 m in diаmeter will be lоaded in tension by a force P. It is known that this force produces a total strain equal to 0.0117 when it is applied. Given the stress-strain curve shown below, which is bilinear, calculate the value of P required to produce that total strain and also obtain the final length of the rod after the load P is removed.  Note that the stress-strain curve is not to scale!
