The diameter of the cross sections AB and BC are alsoindicated. The material properties of the bar are: E - 20 GPa and v = 0.3. If the gap6 =1 mm, then answer the following questions (you can take a = 3.14):(a) Determine wo that results in the gap (6) being closed. (20 Points)(b) If wn = 628 kN/m, determine the internal force in member BC? (20 Points)F7%A4unO
