Wheel

The Mesopotamians are credited with the invention of the wheel. The wheel was a revolution as it allowed larger loads to be moved a greater distance.


The linear velocity of the axle as a function of rotational frequency is:

where
v = linear velocity of the axle [ms-1]
a = wheel radius [m]
f = wheel rotational frequency [Hz]
ω = wheel angular velocity [rad s-1]

Bump

The motion of the suspension as the strut is compressing.

Droop

Total downward movement of a wheel from a static ride height.

Historical Notes

  1. 3200BC Wheeled vehicles are used in Uruk.
