You create a strain gauge from a straight length of copper wire that is 1.00 cm long and has cross-sectional area of 196 x 10-9 m 2. You carefully attach the strain gauge to an aluminum beam that is 10.0 m long. When the piece of aluminum is stretched, the strain gauge resistance increases 27 x 10-9. Resistivity of copper = 168 x 10-6 m. E of copper = 115 x 109 Pa. How much strain did the aluminum beam undergo?
