The diameter of the cross sections AB and BC are also indicated. The material properties of the bar are: E - 20 GPa and v = 0.3. If the gap 6 =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 % A 4 un O
