Variables:
  • L = Column length
  • H = Horizontal distance
  • P = Load (number of pennies)
  • q = Angle of Cable = 45� (keep constant)
  • Buckling happens when:
  • D = L/H
  • D= 24
  • Calculate H = L / D

Graph the relationship between Column Length and Load


Questions:

  1. Did the compressive member that was tested have a bow or camber prior to applying the load? If so, do you think this had an effect on when it buckled and in what direction?
  2. Connect the points plotted on the "Load vs. Column Length" graph. Please describe the line, straight or curved and in what direction. What does this mean?
  3. Based on the results of this test, how will this concept influence your design? Please explain.
