a. A round steel bar with an initial diameter of 20 mm and length of 2 m is placed in tension, supporting a load of 2000 kg. If the Young's modulus of the bar is 200 GPa what is the length of the bar when supporting the load (assuming it does not yield)? b. If the Poisson's ratio of the steel is 0.4, what will the diameter of the bar be when supporting the load?
