Variables:
  • L = Column length = 36"
  • (keep constant)
  • P = Load (number of pennies)
  • H = Height of Cable
  • q = Angle of Cable = Ratio of H/L
  • Buckling happens when:
  • D = L/X
  • D = 24
  • X = Horizontal distance = 1.5"

Graph the relationship between Angle of Cable and Load


Questions:

  1. If the load (P) remains the same on the cable, how can the compressive (horizontal component) force be increased? Please explain.
  2. What cable angle will produce the greatest horizontal component?
  3. Based on the results of this test, how will this concept influence your design? Please explain.
