(7%) Problem 1: Suppose a piano tuner stretches a steel piano wire 6.5 mm. The wire was originally 0.825 mm in diameter, 1.33 m long, and has a Young modulus of 2.10 x 1011 N/m. Randomized Variables 40=1.33 m 1=6.5 mm d=0.825 mm Calculate the force a piano tuner applies to stretch the steel piano wire in Newtons.
