Recently began researching Pedal Powered agricultural machines, more specifically grain cleaning machines. Have found some great videos of finished products. Ultimately wanting to build something to clean and dehull millet and/or sorghum. I am getting hung up on Torque and how it applies after the initial torque from the pedals. If the sprocket on the pedals is connected to an axle with a smaller sprocket, and on that same axle is another, larger sprocket which is linked to something further down the drivetrain how does the initial torque from the pedals transfer to the larger sprocket and so on down the line? Any information or resources would be greatly appreciated. Thank you, Hackers.
