Gear Ratios When two spur gears (or any other type of gears)are in mesh, the number of teeth in one geardivided by the number of teeth in the other iscalled the gear ratio.Teeth #1 Ã· Teeth #2 = Gear Ratio 2. Gear Ratios and Structures Henri deVick A bout 1000 years ago, three inventions weremade in Europe.peed of Rotation, RPM The spinning or rotational speed of a gear ismeasured in Revolutions Per Minute (RPM).If a gear spins completely around exactly 16times in one minute, itâs going 16 RPM. If itspins exactly 1000.9 times itâs going 1000.9RPM.
In good weather conditions, a wolf can smell its prey from about 1.75 miles away. As the pack of wolves moves closer towards the prey, they will maneuver ahead of the prey for final confrontation. Just by its a sense of smell, a wolf can find and identify other pack members.
