The circumference of the moon is approximately 10,921 kilometers.
we know motor rpm, gearbox ratio, gear spoket no of teeth, conveyor pully spoket no of teeth and conveyor pully O.D. Exm- we have a motor of 1500 rpm, gearbox ratio 30:1, gear spoket no of teeth 24, conveyor spoket no of teeth 48, and conveyor pully (head pully) od is 200 mm, Solu- motor speed- 1500 rpm gear output - 1500/30 = 50 rpm conveyor pully rpm - 24*50/48 = 25 rpm conveyor pully cercumfrance - 200*3.14 = 628 mm or 0.628 meter conveyor speed - 25*0.628 = 15.700 meter per menuts
