  1. Dimensional Analysis & Dinosaurs – How fast did they run? Source: http://rainbow.ldeo.columbia.edu/courses/v1001/hot21.html Attributed to: R. McNeil Alexander

  2. Relationship Between Stride and Speed

  3. Non-Dimensionalize the Data Relative Stride Length = Stride Length/Leg Length Dimensionless Speed = Velocity/ (Leg Length * Gravity)0.5

  4. Need Leg Length – Relate to Foot Length LEG = 4 X FOOT LENGTH (to metatarsals)

  5. Results * Upright Meat Eaters (T-Rex) ** 4 legged browsers (long necks)
