  2. S1 E2 - The Science of Structure: Forces in Balance
    March 4, 2011
    33min

  5. S1 E5 - Building Up: Columns and Buckling
    March 4, 2011
    32min
    TV-PG
    One of the most potent human aspirations supported by engineering is to build up. Learn how this has been done from antiquity to the present with columns: structural members that carry load primarily in compression. You'll also learn about buckling: the often catastrophic stability failure that occurs in columns with certain geometric characteristics.

  6. S1 E6 - Building Across: Beams and Bending
    March 4, 2011
    32min
