.Spot.Mechanics.Rotation.GearNoMass

Information

Ideal massless gear. Rigid coupling with gear-ratio

  ratio[1]/ratio[end]

Input identical with massive gear 'Gear'.
Gear ratios are defined by relative speed. The following specifications are equivalent

  ratio = {6, 2, 1}
  ratio = {9000, 3000, 1500}

For memorising

  ratio[1]/ratio[end] > 1 if flange_a faster flange_b.
