Input: red slider of Vr velocity. It carries block of two gears. Tooth numbers: Z2 and Z1. (Z2 is larger than Z1) Output: green slider of Vg velocity. Brown rack is stationary. Green rack is fixed to the green slider. Vg = Vr*((Z1 Z2)/Z1) Here Z2 = 2*Z1 so Vg = 3*Vr If Z2 = Z1, Vg = 2*Vr Inventor files of this video: http://www.mediafire.com/file/yvjez56p54x2918/GearRackIncrease1Inv.zip
