A metal wire 3.50 m long and 0.70 mm in diameter was given the following test. A load weighing 20 N was originally hung from the wire to keep it taut. The position of the lower end of the wire was read on a scale as load was added.a. Graph these values, plotting the increase in length horizontally and the added load vertically.b. Calculate the value of Youngs modulus.c. The proportional limit occurred at a scale reading of 3.34 cm. What was the stress at this point?
