You apply a force of magnitude Fi to one end of a wire and another force F_ in the opposite direction to the other end of the wire. The cross-sectional area of the wire is 8.00 mm2. You measure the fractional change in the length of the wire, Al/lo, for several values of F. When you plot your data with Al/lo on the vertical axis and F (in units of N) on the horizontal axis, the data lie close to a line that has slope Part A What is the value of Young's modulus for this wire?
